In addition to being a huge pussy who can't kill zombies, let's not forget Father Gabriel let his entire congregation get eaten alive while he was nestled safely inside a church eating canned beans the very people he let die donated to the homeless. Yea, that's right, dude stole food from the homeless!
Ron is literally every annoying, angsty step-child ever, plus he's all up on Carl's girl so there's a legitimate reason for Carl to "accidentally" push him over the wall into a sea of walkers.
Speaking of Carl's girl, Enid seems pretty expendable. Hate to break to Carl but teenage love doesn't usually last long, and I doubt the chances go up drastically during a zombie apocalypse. Let her go Carl! To save Glenn, it's worth it.
