I have never done the following so I cannot verify its effectiveness, but I would ask the family to sit with their eyes closed (for focus only) and concentrate on the ill person. People take it in Random turns to recall an incident involving the ill person , or an anecdote, or a favorite 'anything' about the subject and try to spark a discussion about what value that person has been in life or what would make that person want to live longer by valuing what they value. In this way you cut out god but do what prayer is trying to achieve,so no miracles , nothing may happen as a result of what you do. but something practical and real may happen - like spark the desire to open a photo album or just relate another forgotten[ by most] story. Something good emerges only when you do not give up

what if i prayed for the individual to die technically im a murderer but as i never liked this individual should i care

I see it but how would anyone know if you prayed? I simply do not believe televangelists or politicians who say they are praying for you. God's plan is in place. Just imagine a written prayer with a blank name inside it. You simply pick the type of prayer needed and fill in the name. It should work as good as any.

When all is good, give God the credit.
Satan (& humans) get the blame for all "bad" things.

Simple enough......until the lawyers are involved.
(Then it'll be their fault too......only god wins here)

That's because thesists don't really believe the stuff they say. It's just habit and conditioning, but if they really believed that stuff they'd never go to the hospital or doctor..just pray.
