Also I think that its worth noting that for 2 biggest religions, this life while it is a test, its also important to note that if we improve this life and conditions for it for us and other people we would also downsize evil and increase good in people.

If a religious person feels the need to sacrifice themselves for others by sometimes doing some bad, then maybe its not as bad to do bad sometimes? IDK

Im sure God takes this into consideration.. so I guess its not that huge of a difference between religious people and atheists.

Now occasions where one would act morally superior because of afterlife would be for example not snitching, arguing with a judge coz you know you are morally superior and God's law is above the government law, then also not accepting deals because you should love yourself and you deserve better, etc.

Id know because I am dealing with some similar struggles.
