Those who fail to accept the free payment of their sins, paid by Jesus's death, go to hell because they are still in the prison(place) of sin.
Once you accept Christ you are moved into the place of righteousness.

All the bad deeds are not what send you to hell. The punishment for those sins were judged and punished in the body of Jesus Christ at the cross.
It's what you choose to do with Christ that determines your ultimate fate.

May God's grace find you
