I mean, it's not really the whole hero organization more as it's just Hawks because Hawks was the one to kill Twice and he was technically working alone (what with being undercover and all). I do agree though that killing Twice was a bad decision, though, on Hawks' part. Twice was already incapacitated and the other villains would have had to save him and bring him somewhere, giving the hero's reprieve for a little while. Now, you just have a bunch of villains angry and vengeful over the death of one of their own AS WELL AS the Shigaraki situation. I think Hawks could just see that he was losing and did something drastic, but ultimately, it kinda made things worse.
I'm just saying but I previously said that killing Twice was a bad decision...and hey would ya look at that! I feel like I'm getting more right by the second. Cuz now Toga's going berserk! What even is the plan here???? To make the situation worse than it already is??? Whoever planned this had to see this coming! Do the hero organizations think that the bad guys don't even care about each other???? Like things are just not adding up...it's kind of silly how terribly this is going... (Maybe the hero organizations aren't seeing the other side as much as they should be??) ( ̄へ ̄)
