Did Matt kill people in the building, tho? Do you mean actual real people or Hand, because Matt was okay with killing the Hand in s2 when he went after Nobu, but I think Stick convinced him about Nobu not really being a person anymore when he talked about Nobu having lived for several lifetimes. Matt kicks Nobo off that ledge and he sees him lying down there, dead, and Nobu comes right back to life. Matt knows he can't kill these people. That's why he tells Danny you can't stop these people, even with whatever your fist does. When he offers to help to blow up the building, the only people left in there are the Hand, he makes sure of it. I don't think it was clear at all but Matt killing a normal person isn't the same as killing the Hand. That's the way it is in the comics, too. Matt/DD 'kills' the Hand constantly because they're not really 'alive'.

Holy crap, you're so right about Matt, Karen, and Foggy being toxic for each other. I agree with you, it's why I love DD too because these are not basic cookie-cutter relationships. All of these characters have some serious issues, and they love each other but they're terrible for each other too. Like reading the original post here is about Frank doing a lot for Matt, and it's true. They hurt each other and rescue each other but there's legit respect and understanding there, and some of those things don't show up in Matt's other relationships in the same way. Everyone is so complicated and twisted, messed up, like the relationship with Stick and Matt and Elektra. GOD. It's amazing tho, I love it.
