what would completely break your character?
That’s hard to imagine, as Loki is a ruthless survivalist. My closest guess would be for both Thor and all of Loki’s children to die simultaneously and because of an error Loki made, particularly an enemy who wanted to exact vengeance upon Loki by harming his loved ones. I believe this because losing Frigga under those circumstances (in part because he gave Kurse directions out of the Asgardian prison and unwittingly straight to Frigga’s chambers) already nearly broke him.
