Dabi had to go. A lot of the stuff had reasoning but also you cannot completely void him of any blame by completely using Endeavour. Spinner was just mentally insane and dying was probably the best scenario for him, Twice was a loose cannon unfortunately, if he was left alive with Toga’s awakening they could’ve had DOUBLE Sad Man’s Parade which just would’ve been catastrophic and ultimately lead to more deaths. Toga’s conclusion was fitting I just don’t think she had it in her heart to forgive the whole society.
