Is it over the top, though? Can't set him free. He can easily recruit people, and retaliate. You'll have another prison showdown. If they lock him up, nothing will change. He'll be consuming resources, and will still pose a risk. I think Rick is getting crazy but I also think he's right for the most part. He gave the wife beater a choice. Rick had multiple opportunities to take him out, already. I know Rick has had it out for this guy since he first saw him. He went for his gun on first sight, almost like a reflex. I wasn't sure if it was because Rick is going crazy, and wants the woman, or maybe Rick could see that he wasn't a good person from the second he set his eyes on him, and it was his instinct that caused him to do it. Rick is extremely sharp, almost on a superhuman level, at times.
