I don't want to go pray for my dead cousin
Why don't you want to go pray for him?
Because I don't believe his soul is in heaven if he did drugs all his life.
It's okay if you don't believe in prayer but if you believe in God don't you believe he forgives? Prayer hurts no one but may make you or his family feel better.
I don't give a damn. I'm not going to pray for him.
If you don't want to you don't have to. Perhaps you can find another way to support your cousins family.
