A Thief on the other hand, is sneaky - so they avoid stuff, and are thus of no value.
I agree on this point. Lee is living proof that a convicted killer is capable of caring for a child and helping people out. Shit happened for him. He lost control and he killed someone.
Stealing meds is another matter altogether. It's a calculated move. It didn't matter that Ben had good intensions - the fact was, he stole from the group when he should have consulted them about the dealings with the bandit.
I'm not saying that Ben is an evil person that deserved to be killed, but anyone who puts thought into making decisions that are detrimental to the team is of no value.
