>inb4 muh free will
First of all, free will is entirely debatable in a deterministic universe. Secondly, if God is omnipotent he could create a reality where humans can freely choose their actions but divinely intervene when those actions unfairly harm others. Thirdly, not all suffering is caused by human will. What about natural disasters, diseases, accidents etc.? Why doesn't God prevent them from causing unnecessary suffering and death?
