if tsunade dies i'm guessing her death will probably trigger so much anger in naruto that it'll give him all the strength he needs to defeat madara and obito omg i can see that shit happening but really it shouldn't happen adkfjwer
oh, you are certainly right! that would be a trigger... but i wouldn't want that to happen? it would be too predictable.
tbh considering how long naruto is as a manga, kishimoto really is careful with deaths. CONSIDERING EVERYTHING. he isn't ruthlessly killing off characters, even tho deaths happen quite often (sigh... one word: akatsuki), but i think they happen with a purpose, as a very strong plot device (for example itachi) or as a mean of character development (asuma for shikamaru or jiraiya for naruto)
one of the reasons of why i also wouldn't want tsunade to die is because this manga is so rarely focused on female-female relationships (in fact it almost isn't at all), that i wouldn't want to see sakura experience tsunade's death. i see tsunade as more than just a potential trigger for naruto's strength. i think it would be very hurtful to tsunade as a character and it would just show how inconsiderate kishimoto is with handling female characters.
