I think there is a fundamental misunderstanding that neither side is addressing...
Atheists think that if there is an all loving and all powerful God he must prevent suffering. This idea suffers from confirmation bias just as badly as many statements and beliefs Theists make.
Can you prove to me that perfect love must eliminate all suffering... and not only that must do it right this minute? Maybe love and suffering are compatible in some way that we can not fully understand here in our temporal existence.
To say suffering is bad and love is good is to simply just confirm how it feels to experience it. However your feelings on the subject don't create a moral absolute on the subject. Sometimes good things feel bad and bad things feel good. We can't go by how things feel when it comes to judging them.
