St Peter had those moments of normal human cowardice when he denied knowing Jesus to avoid trouble. He regretted this but showed his devotion ultimately dying a martyr. Judas was a traitor and His story didn’t end as well.

Now since it’s hard to sort out people in the swamp, might I humbly inquire, but not as a call to do it posthaste, KILL THEM ALL, LET GOD SORT IT OUT.
