if Hopper was a true CM he'd do an Alan Yates and kill his loved ones even if he felt slight guilt over it (like Joker kills pretty much anyone as well, even Batman.. he feels a bit "sad" when it comes to killing Batman (since he views Bats as a "friend") but CMs are still known for the "kill friends and loved ones, even if it makes the CM in question slightly sad" - they then normally go right back to being completely remorseless).

Bringing Joker back, remember how he got really sad / angry when it was believed some random guy actually killed Batman? he also mourned the "death" of Captain Clown ("You KILLED Captain Clown!").. yet like I mentioned before after that moment of guilt / sadness he goes right back to not giving a crap..

that's a CM, really, they may feel a bit upset about breaking certain codes but they'll still do it anyway (.."ah heck, I'll laugh anyway").
