I wouldnt say all religions are evil more organised religion can be used very easily for evil as it insights others to follow a cause. In exactly the same way a corrupt leader can do so with a nation except organised religion can do evil deeds hiding behind a mask of righteousness.
I personally have a problem with organised religion because of how afraid a species we are and how we will do ANYTHING to cling onto an idealogical cause, even kill. People aren't able to except the idea that there's nothing after death or that life is trundling along with noone behind the wheel so they cling to the first voice that says amen.
I just believe in nature and the endless recycling of everything. I do believe in som kind of existence beyond death, we arent dumped on this earth to attain knowledge and experience for it to be wasted, nature abhors waste in every aspect of life so why would it be the same with intelligent thought and idea?
Whatever ever is after death it wont be even remotely close to any religions idea of heaven.
