What I'm getting from this is that Hirelings are just 12 more dead bodies, unlike Companions, I don't have to worry about setting them on fire or hurting them, because I won't have to feel bad about them, when I do it,

"Come on hirelings, I throwing one of you at bad guy 1 who is stuck in the grease area, then on my next turn, I'll just toss fire ball without worrying about collateral damage, it's not like you guys will turn on me or anything since I'm paying you to die for me."
