God does not send people to hell based on emotion but law. Break the law and if it demands it, the judge has to punish the lawbreaker no matter how much he loves them. God’s law is one with His nature and demands sin be punished. That’s why Jesus was punished and died for sins on the cross – to fulfill God’s law so a pardon could be extended to those how would receive it.
This type of question often implies it is contradictory for a loving God to send people to hell. It’s actually contradictory for a loving God to ignore His law and justice by automatically rewarding lawbreakers with heaven.
