rin's death was kind of an accident waiting to happen

[Ultimate Sage Power]

what i mean by this is in the kakashi gaiden manga(about team minato's life on the battlefield during the 3rd ninja war),i can't remember what chapter it was but rin was kidnapped by rock ninja who tried to use some sort of genjutsu to extract information from rin but rin who was strong willed resisted their efforts and obito who had just awakened the sharingan and kakashi rescued her and some time after tragedy struck team minato and obito was crushed beneath rocks after he saved kakashi from being crushed by the rocks,obito had rin transplant his left sharingan eye in kakashi and in what was believed to be obito's final words before his supposed death(which didn't happen cause he miraculously survived) he made kakashi promise to keep rin safe but some time after(days,weeks,months whatever) according to zetsu kakashi and rin were surrounded by enemy ninja who were jonin level anbu and in the situation kakashi and rin were in they were out numbered and with rin being a medic ninja it was kakashi's duty to keep her safe but like i said they were outnumbered and kakashi who was trying to protect rin as he was the only one of the 2 who could fight them off was tired, the enemy ninja used this to their advantage and possibly tried to capture rin to either extract info from her or for some other unknown reason and with the situation kakashi and rin were in kakashi had to act quickly, he could either let the enemy capture rin which could be dangerous to the leaf or other villages depending on the reason for rin's capture or kill her, and as we all know it's obvious which option kakashi chose,YES YOU GUESSED IT HE KILLED HER! and this action shocked both rin who realised kakashi fataly wounded her and kakashi who had no choice and this could be the reason why the enemy ninja said "shit he got us, after we worked so much to get it!" and it's because of this reason why obito who was also traumatised by rin's death said when kakashi asked him why did you turn out like this! "IT'S BECAUSE YOU LET RIN DIE!".
