What i love most about this, is that even when Green Lantern is told his family is gone, he doesn't become filled with rage or fear. He keeps cool and understands, that even if he wants Braniac dead, it's not the right thing to do. He can't risk other lives just so he can feel better.
16:16 is such a saddening moment. It gives you just a glimpse of the good man that Clark used to be, before everything was ripped from him and became the monster he is now.
Exactly the reason Batman had a contingency plan, he even got one for himself, just in case he went rogue and became a threat to humanity. In a way I'm glad they showed us that Batman was right.
Theworst part of this is that BOTH sides have a lot of right points. Sometimes a person is to far gone and to evil to keep alive, but that line of thinking is also super dangerous and destructive to the point where it prevents you from seeing where it ends and where people can change. Harley is the proof that Bruce's methods do have merit, whereas the joker is proof that Clark isn't entirely wrong either.
Spoken like a true villain
