The world is open to personal interpretations. There is not an evil, as we have been programed to believe in good and evil. It is from the perspective of the impacted, how we choose to define events and changes in life

evil would imply there's a devil

How do you know what's evil, or good?
Have you ever done something you thought was going to be good and had it come out bad?
Or, do something you thought was going to be bad and had it come out good?
How do we know the true outcomes of anything we do? Maybe we do something completely innocuous to us that has a destructive effect on someone else we don't know?
It takes just as much wisdom to be truly evil as to be truly good.
Remember when you were 3 years old and you wanted some candy? But, your parents wouldn't let you have the candy? To you, in your 3yr. old mind, that was evil. How could your parents not let you have what you wanted? Your parents had better vision than you and didn't want you eating only candy.
There are a lot of things that happen that we don't like but that doesn't make them good or evil. To know good or evil takes the ability to know the real outcomes of events.

It's all relative. When the last star flickers out in the inevitable heat death of the universe, who will be there to give a shit about genocide or rape or stealing four dollars in quarters to play the arcade? What morality? What entity?

All that matters is pain and pleasure: the most tangible basis we have for any sense of good versus evil. How much? Intentional? Who to who? How many? What kind? What's being traded/sacrificed? Why? Even then, it just matters to us, right now. We're nothing more than apes on a rock and I think we'd be better off embracing that idea than coming up with transcendent forces or whatever.

Evil. which is actually a religious word could be identified as cruelty in all it's forms and degrees. Cruelty is a total lack of empathy for others. Well that's my 'take' on what evil is.

Evil is a concept, not a concrete substance or entity. It exists, but only subjectively.

The question assumes evil exists.

Evil as in Satan? No. But there are people on this planet that have a skewed version of Right and Wrong, which can be viewed as evil.

My personal opinion is that good and evil are like hot and cold; cold is the absence of heat. Evil is the absence of good.

Evil does not exist as an independent malevolent force descending on a site or on the world. It exists only in the intentions and actions of individual humans and groups of humans and in the effects of those intentions and actions.

No evil. People that have been damaged by some form of abuse and some with brain defects. Some have been taught to hate, fear, use, and abuse.

Personally I would think evil's existence is subject to perspective.

tRUMP is evil.

Evil is a word made up by theists to describe things they don’t like.

How about corrupt or unethical or vile?

There's knowing right from wrong. There's no evil in this world. Just a lot of stupid people.
