Even in the case of an immoral criminal who must suffer the consequences of their actions, it still begs the question why and how such vile acts were permitted to begin with or why such a vile being was allowed to exist. In our depths of despair, it becomes necessary for some to believe in a higher power or conjure a godlike entity, in order that they may still hope and believe that their suffering were not in vain.
The only thing I believe in is the first statement I wrote above. There are a lot of different takes on why suffering exists. This is my take: it shouldn't. The only thing that gives me hope is the idea that any and all sufferings are unjust and justice means an elimination of such in all its forms. Until want, despair, poverty, abuse, and any and all types of corruption are definitively and completely eradicated, the work to bring about the end to that which should have never existed must never stop.
