Rusty idolizes Red, and apparently, he's looked at as being a genuine hero in-universe. However, given the way Red behaves in other Dorklyvideos, and if you believe all Dorkly videos are canon in some way, it's easy to see part of the reason why Rusty is so clueless and destructive most of the time.
It's doubtful considering how most of those versions of Red are usually either just as incompetent or as callous as Rusty when it comes to handling pokemon. In the latter's story, Red actually seems a boatload more competent than his other Dorkly incarnations. Definitely more overkill when it comes to dealing with Team Rocket, but then again they act more in common with an actual crime syndicate than in the original games so lethal force against them is arguably justified.
It makes sense for Past Rusty to be the one to undo the damage caused by Rusty's stupidity: There was no one else who could match Rusty's unpredictability except himself.
Rusty being a pretty warped individual makes sense when you consider that he grew up with just his folks and thus has No Social Skills.
When Rusty meets the Elite Four, they state that he cannot challenge them without eight badges. Rusty calls for his Super Bidoof Peanut Butter who then appears with a bloody sack full of badges. He the state that all of the badges in Kanto from any trainers that held them were in the sack. The thing is that Peanut Butter's choice of words is very vauge and from his words could mean any gym leader that give out badges and thus holds them, or literally ANY trainer in Kanto with Pokemon badges, including trainers that won them from Pokemon gyms.
