>>98726422>The turtles are just minions sent to deal with someone else's problem in this scenario.The blood feud between the Foot and the Hamato is a super-underexplored element of TMNT overall, but it was a big part of the original comics.
Oroku Nagi attacks Tang Shen, Hamato Yoshi's wife.
Hamato Yoshi kills Oroku Nagi.
Oroku Saki, Nagi's brother, grows up, trains, and kills Hamato Yoshi and Tang Shen.
Splinter, Yoshi's pet rat, trains his adopted sons, they grow up to kill Oroku Saki.
The Foot declare war against the turtles for what they've done and are a perpetual thorn in the turtles' side.
It isn't until they strike a deal with Karai and help quell the in-fighting between Foot factions that the turtles are freed from the cycle of violence.
It's a super fascinating story. By the time the turtles challenge and kill the Shredder, all the original participants in the inciting action are dead. It's violence begetting violence. The turtles inherent an old grudge. That kind of moral ambiguity is what made the original Mirage comics so compelling.
