Deviled Hen
I do believe that motivation based on an after life is very dangerous but I don't think that being a Christian means you believe this and also this problem exists outside of Christianity.
Yes, it would seem the problem exists outside of Christianity as well. Look at how misguided terrorists are led to kill innocents, because after all it will send them them to Paradise to "martyr" themselves that way.
I think the real problem is not over emphasis on the next life but the impact that this will have on the valuation of this life. It is really when people begin to believe that this life is relatively valueless that the potential for harm is created.
Yes, at the extreme you get "Kill them all -- let God sort them out."
Even before you get there, though, you get people like my neighbor lady who was so worried about getting into Heaven she though she had to read her Bible all the time -- so she got her 12 year old up at 4am to do her housework.
The notion of an afterlife need not be negative or devalue life, though. It depends on what else there is to balance things out.
Atheists suffer from this problem just as much as theists.
In what way?
