No need for shooting them. The first got killed by his own scalpel and the others suffered death from a bit harder contact with the walls.
Yeah, i remember Joel said something like "You would just come after her" before executing Marlene. Looks like he thougt of the same risk if he would let her live.Sarge034 said:Actually, she stood in your path with a gun and then lowered it so she could take a hold of Ellie. As for finishing her off... Never leave a combat capable enemy on the battlefield and never let a fanatical enemy live. It never works out well. If he had let her live she would have healed up and spent the rest of her waking days searching for them. This would put the entire community at the power station at risk. It was just safer that way.
It looks like everything else just comes down to personality types, personal morals, and beliefs. Nothing wrong with that.
