As for the first one - it doesn't matter. Like I said, I don't care "why" only who. I don't care if they were justified, or enchanted, or tricked - I just want a name. As for the second, I think it's what Finn would have wanted, and it's definitely what I want. I don't necessarily have to use that sword, I can use the other one or, (I'm assuming this is set in the States) I can pick up a shotgun at Wal Mart. If I can't have revenge, then I just want nothing to do with the Templars at all (collectively or individually).
I know we are discussing fictional situation in fictional world (in real game) but ability of logical thinking is universal.
You need to know concept of hierarchy. She was sent to the mission
by someone above her and if that mission was clearly against Templars like breaking into their HQ and steal something, there were other
Templars with orders as well. As they say,
don't kill the messenger.
The fact alone that you (and me, and some others) think so highly about Finn should give you hint that she actually probably would not want you to avenge her. Why? Because when we met her she was exactly as you are now, full of rage and anger. In time MC and Finn got closer together and she has shown some humility, admitted she was wrong. Before she met you she would go rogue but now? Not sure. She changed mainly because of MC so MC doing two steps backward and acting like she would back then feels kinda like betrayal. If she changed because of you, that means she think that's a better way than just raw rage and revenge.
And as I said, we need to know what exactly happened. If she could be actually spared and be jailed instead but someone decided to just kill her (like we could at the beginning) or simply she was ambushed on some neutral-like mission then yeah,
you've got my sword and my bow and my axe and we will burn them to the ground. Context matters.
