“Would I see my abuser in heaven?”

A serial child rapist and murderer spends years destroying children’s lives. Before he dies, he genuinely repents and accepts Jesus, so according to your beliefs he goes to heaven.

Some of his victims or their families, however, reject Jesus because the trauma he inflicted destroyed their faith, so they end up in hell.

How is that perfect justice? Why does the man who caused the evil receive eternal paradise while the people whose lives he shattered face eternal punishment because of what his actions led them to believe?

Ps- this happened near my village in nagaland, India. He died and a diary was found where he confessed etc. He even repented.
