What did the Turtles did was stupid, they should have talk to Splinter about this.
What the turtles did is something like the Elric Brothers did in Fullmetal Alchimst (2003) series. The Elrics fouce on Scar rather than the homunculus (the homunculus were the serious threat than Scar.)
The turtles are stupid
If you think the turtles are stupid, why are you on this wiki?
not the point, I meant that their decision on trying to take out the Shredder instead of the Kranng and betraying Karai was a stupid move on them.
Raph, Donnie, and Mikey thought Karai couldn't be trusted and thought she might double cross them again like she did in "The Alien Agenda". I felt bad for Leo being forced to agree with them on that.
Karai is seriously messed up. I can get why the 4Kids version of the character felt that she and Leonardo were friends. Here, not so much, given that the whole of her interaction with him has consisted of her trying to keep him off-guard and off-balance, and generally, treating him as a disposable pawn. If that is what she thinks friendship is supposed to be like, I do not have that much sympathy for her “I thought you were my friends” angst.
They didn't try to take shredder INSTEAD of kraang they tried to take BOTH out in the same day which was VERY smart. Taking down the enemy is what they are supposed to do.
The turtles will need to redeem themselves for this.
They don't have to redeem anything. They tried to take down the bad guy that was trying to kill them. They don't need anyone's permission to protect themselves. And technologically they didn't betray her at all they didn't know that he was he father they had nothing in the agreement not to kill shredder.
