God is timeless

[Neo-Scholastic]

for their shame of their sins. in hell they would think of what they have done wrong, which would cause them to feel shameful of it. here in this world, we are able to forget, but not there.

So someone who kills someone, but believes in Jesus, will go to heaven and there they don't feel any shame about their prior actions?

If they believe if Jesus they wouldn't kill someone.
