Do some people in this fandom genuinely not know c!Techno wasn't being serious when he said he was "peer pressured" into executing c!Tubbo?
He was joking because that wasn't true! It was an understatement! It was comedically diminishing what had just happened, and that's what the narrative itself framed as him being threatened and having problems with anxiety! He was just ordered to execute an ally by a dictator who seemingly had an entire group of people by his side. None of Techno's own allies would help him.
That's not "peer pressure", that's what we call being forced to decide between killing and ally and possibly both of you being killed as well as the entire operation compromised! It was the trolley problem and Techno pulled the lever. He would rather be directly responsible for one person's death by action rather than ruining everything and possibly killing more people by inaction. Saying c!Tubbo's death is "his fault" is not 100% factually incorrect, but man is it unfair.
And please don't say "he took them on later on and started shooting into the crowd", that's entirely out of context and removes the fact that he didn't know how the fireworks would work, and they ended up killing both Schlatt and Quackity - hence it was reasonable to assume the crowd would be after him and a fight would ensue, so he started preemptively shooting as to get as many people as possible so they wouldn't run after him.
"Peer pressure is a pisspoor excuse for murdering someone" Well yes because that's not what happened! It was a god damn hostage situation if anything, and although c!Tubbo didn't deserve to die, c!Techno also didn't deserve to be forced to execute him.
