He totally gets it.

I'm one of the few people who liked Affleck as Daredevil. The first time I saw the scene where he (Daredevi) let the bad guy get run over by a subway in an act of outfight vigilante justice I was impressed with his bad-assery. I thought then that he would make a good Batman. Prophetic.

wait what, Seth?
"Superman is like I won't ever kill people and Batman is like you do what you gotta do"

Er, no. Not at all. Batmans whole schtick is not killing. Ever.
Not even the joker.

glad I wasn't the only one who did a double take when I heard that.

I think he meant that Batman isn't above breaking bones and dishing out more hurt than necessary at times whereas Supes wouldn't do that.
And, while Batman won't kill, he also 'doesn't have to save you' whereas Supes would never allow someone to die through his inaction.
