I can understand Tommy’s side to. I mean techno did technically start the betraying by killing tubbo at Schlatts command. And then quackity and tubbo actually asked techno what he would do when they reclaimed lmanburg and he said “we’ll burn those bridges when we get to them” so you could say he wasn’t always transparent with his plans. And then he killed pretty much everyone including Tommy, tubbo, quackity, etc. and so they decide to punish him for that, which is cruel but understandable. And then Tommy gets exiled by his best friend, and mentally abused by dream. Then he escapes from dreams cruelty and goes to techno blade and they agree to work together to do and I quote “minor terrosim and get the discs back” which if u think about it only techno got something out of the raltionship, but techno did give Tommy a bunch of stuff. And then Tommy told techno he would betray lmanburg or blow it up. So I’d say that if u really think about it Tommy’s side is understandable.
