Alcoholics Anonymous should be on the list.

Currently the worst set of practicing ideas is called "islam."
An average of 4 attacks PER DAY since 9-11 in the name of a dude dead for 1400 years. A true mental illness.

Religion, any religion, is a system of empty signifiers, and its definition/identity depends solely on interpretation, who does that interpretation and for what purpose(s). Therefore there are as many Christianities as there are many interpreters and the same applies to Islam, Judaism, etc. Thus it is just impossible to label one religion "bad" or "good" without putting into consideration that very specific interpretation.

I would like to add another one to your list if I may, though it is not usually thought of as a religion which is perhaps why it is not on Wiki as such. And that is Art especially with a capital "A", because it is the enabler in manipulating human minds which spans all of the religions. It has a so called spiritual worth for which there is no evidence. And that spiritual worth leads to the idea of "artistic truth" which is not connected to any objective truth but carries great prestige and can be used to validate any lies that any other religion wishes to sell. I know this this will not be popular with some even here who worship it though, tough.

I was raised as a Buddhist and I loathe it. I wish westerners would stop thinking that Buddism is a philosophy. Of course there is some good philosophy in Buddism- same as other religions. The fact is that Buddism is definitely not a philosophy, it’s a religion full of Fear and BS- hell, heaven, merit, sin, karma, reincarnation etc. Though Buddism doesn’t talk about God, it uses karma and reincarnation as a moral cause and effect- just like God watching/judging/calculating how much merit and how much sin we bank into our accounts before sending us to hell (yes there is hell in Buddism and people are very much afraid of it) and then rebirth as a human or an animal.
There are a lot of misogynistic beliefs in Buddhism. Women are viewed as lustful temptresses- evil and dirty.
Buddism is an offshoot of Huduism. Buddha was raised as a Hindu and he was obsessed with Nirvana/Moksha. However, only the top caste could achieve Moksha in Hinduism. He found “Buddism” so that every caste could achieve the idea of “Nirvana/Moksha” He was a revolutionary and a philosopher, but that doesn’t mean his beliefs were true. He wouldn’t believe in reincarnation, hell, karma, Nirvana if he wasn’t raised as a Hindi.
I believe Buddha suffered from an anxiety disorder. His obsession in Nirvana made his anxiety worse. He then discovered deep breathing could calm his CNS and get rid of the anxiety. He also discovered that staying away from too much stimulations (love, greed, hate, lust) could help with his overactive nervous system. He declared that he achieved Nirvana= the anxiety is gone.
Buddhism is not the same as cherry picking philosophical aspects in Buddhism. Buddism is full of BS and it’s definitely not better than other religions.

Islam is a bigger threat to the world than Hitler, Stalin, Pol Pot and all of them put together.

All religions, regardless of beliefs, are terrible. Religions divide us and attempt to control us by guilt. I don’t know of a benign religion. They all foster them v. is. Some espouse peace and non violence but they still divide and attempt to control thought and actions.

Evolution being my one passion, I tend look at religions in a different way. Intelligent life needs purpose survive; it is the food on which an intelligent species feeds. Instead of asking which is the worst religion, I put them all on the same level, because when looking at the big picture, though they appear be segregated, this is an illusion. In the grand scheme of things they are acting as one, it is what is needed by nature. (Evolution) This is why there will always be different religions, that is until the time comes when we will realize this and maybe then it will begin its decline, which I think has maybe already begun. This proves that religion is man-made.

Funny. Luciferianism is not on there. Think about it...

Any religion is peace and love while minority, and as soon as it gains majority and access to law enforcement/army it turns into a weapon.
Christianity is not more evil by itself, it was just the religion with access to bigger guns.
The same happened with other religions that in their region achieved hegemony and inside its borders or to the people around them they were as bad as we see Christianity. Judaism did pretty nasty things given it's limited power, there are many genocides in their sacred books (and in the bible by consequence), so give them more power and imagine what could happen (and what Israel is doing now).
Point is that most of those religions never achieved an hegemonic region or time , or we do not have registers of it to see what they would be like.
It is easy to be peace and love when you would turn to be the weak side of a religious war.
Even in Christianity, the reform and the division between protestants and roman catholics only happened because big leaders with access to armies changed sides, before that the proto-reformists were just praticants of heresy.

Atheism for sure. It’s not a religion so it’s a terrible pick as far as religions go.

They are all bad in some form or other.

Islamic justice is brutal in keeping with the period and location where it was developed. Judaism is almost as bad and maybe worse, except that modern Jews don't follow the really cruel injunctions. Christianity, like Judaism and Islam has a horrific blood-soaked history, which they hypocritically blame on atheists! Most strong Christians are still Nazi-wanna-be s, as has been made clear by the evangelical support of Trump. It would be nice to point to Christians evolving their sensibilities, but clearly that is limited. And those carrying water for the Saudis make the same claim about the Israelis. Except that the Israelis do go to great lengths to moderate and target the killing of Hamas fanatics.

Christians also commonly call out atheism as being responsible for the millions killed by Stalin, Mao and Pol Pot. The problem is that the victims weren't killed for refusing to believers in atheism, but rather, for refusing to adopt Communism (or refusing to kowtow to the communist leader). That is a huge difference, and is not easy explained to the common idiot.

On occasion, Christians are happy to confabulate the Nazis as being atheists too. Yeah, I wonder what percent atheists were present in Nazi Germany - - even one percent?

No way to define "best" or "worst".

judaism is dangerous b/c of their fanaticism & belief that they are the chosen.
they have fucked up the world more that all the other religions combined.
now control the US financial system, therefore the world.

Any that believe in a "god" that needs them to tell you about it.

Judaism invented monotheism (one true god), spawned Islam, Christianity, and all their offshoots, so that gets my vote.

Any that evangelize, indoctrinate, or kill people who do not believe it.

How are we measuring "worst"? Amount stolen? People killed? Lies told? Knowledge destroyed? Views on women? Ignorance spread? Hatred fostered?
