“god”?

Can anyone explain this dilemma to me please? There is the belief by people in “god”. We’re told that this ‘created humans’. Turns out that, whatever you say about ‘choice’, humans have the capacity for endless cruelty. Obvious examples: naz*s, putl*r, the ru**ist army, the iranian ‘morality’ polic*, school murd*rers and many many more. Why do people worship something that created something that can display such cruelty? Such hideous imperfection? That can’t even protect against abu*e in its own churches? Why? How?
