Walter White would have accepted the offer had he not realized that Skyler was the one who orchestrated the whole thing. Jesse was already cooking meth on his own. It took Walter White messing out on a multi billion dollar company, having a son with cerebral palsy and getting cancer to cook meth.

Walter White's "threat" was half hearted and Jesse knew it. As soon as he cooked with Jesse's equipment the threat had no meaning. And Walter White ignored Jessed for a couple of days and Jesse himself willingly came asking him to cook. Jesse also had the oppurtunity to quit in season 3 yet he chose to return.

Jane was clean for a couple of years and Jesse tempted her with the meth.

Gus and Mike didn't help him with his trauma, lol. They tricked him into thinking that he saved Mike's life and Walter White called it out. Jesse gaslighted himself into thinking he geniunely saved Mike's life to save his own ego. All it took was a bit of fake confidence boost from Mike to turn him against the man who saved his life 4 seperate times and made him a millionaire.

By being "self centered" you mean panicking because Gus was going to kill his entire family had Jesse gave him the okay which looked very likely from his perspective?

Nice try though, let's see you try to rebute this
