I just thought of something funny. At the moment where Jiren's backstory was revealed, literally all the fighters left in the ring were orphans. Goku, Vegeta, 17, even Freeza unless he still has a mother kicking around somewhere. No wonder they didn't care about Jiren's sob story.
Jiren: And that is my tragic story
Android 17: Big deal. Me and my sister were orphaned delinquents who had their humanity robbed by a deranged scientist who wanted revenge against Goku
Goku: I kind of accidentally killed my grandpa without knowing it. Also, all of my friends have died at least once. I've died twice, actually
Piccolo: I was behind one of those deaths actually. It allowed me to be finally free of the debt to kill him I was literally born to, given I am the son of what amounts to the Devil
Roshi: His father killed my mentor, after causing an apocalypse I lived through
Gohan: My uncle tried to kill me, I've been thrown in warzones for half my life and my father's been dead a good portion of my life
Krillin: I've died three times
Vegeta: Frieza destroyed my people, made me his lackey for years and tortured me to death
Frieza: *scene missing*
