[Phineas and Ferb] Why does Candace Flynn really want to bust her brothers? What does she gain from that or what have they ever done to her?

I think it's just the sunk cost fallacy. She just started by tattling on them a couple times because they were putting themselves in danger or annoying her, but everything was hidden away before their mom got there. Her mom dismissed the idea as ridiculous, because how could a child make anything more than a LEGO house.

She tried to prove she wasn't lying and then it happened again and again. Now she's at a point where she's spent way too much time and resources trying to prove their shenanigans.
