>implying Trinity would had survived the Arius coup if it weren't for Sensei
friendly reminder back in that chapter Sensei was irrelevant, the pathetic adult that got on all fours to lick Iori's feet to get meager support against some mercenaries bullying Abydos. Sensei had no relevant feats or was worth much trust during that chapter.
Now, if you take Sensei out of the question (who clearly got underestimated a lot by Makoto), Trinity would had fallen and Gehena would deal with the Arius remmants along the GSC who by then would be forced to play a part since it already escalated into a mayor problem between schools.
The part where Makoto fucked up hard was not knowing Maestro and the red bitch where behind the scenes supplying Arius with an army of hot zombie nuns. Otherwise sacrificing the prefect team over Trinity imploding over itself was a worth sacrifice.

>You said Makoto wanted to avoid a world war
literally >>536062171. Trinity was already attacking Genehena through diplomatic tools. War was on it's way and was forced to react to the aggression
