The existence of hell is pretty contradictory to the message of Christianity. That always bothered me, even when I was, like, 8.
Which was like the entire point Jesus was trying to make by the way.
Theres a school of thought that Christ was less messiah and more Jewish reformer. And its through that lens that he makes the most sense.
Arguing that ideas like hell and titheing and practices like the rich getting the best seats in the synagogue are the things he was railing against. This naturally posed an existential threat to the ruling class of rabbis so they had him killed, the end.
Only an opportunist like St Paul turned it into a proper religion of its own and not the counter culture reform movement that Peter was leading.
Fun Fact: "Saint" Paul was literally the Antichrist.
