"Some religions permit you to be evil all your life, but one quick confession on your death bed and all is forgiven and you can go to heaven."
How dare you slander "the one true" church like this.
I believe it needs to be a lengthy confession.
Additionally, high probability of a penance of saying 10 "Our Fathers" and 10 "Hail Marys".
And, as precondition to all of this, having a truly contrite heart.
So not really so trivial.
