Jesse was a dumb kid that was in way over his head. He eventually grew into a solid man (in terms of the show). Is everyone forgetting how well he was doing after Mike took him under his wing? Mike obviously saw something worthwhile in him and I would say he was pretty good at sizing people up. The Fring's revenge episode in Mexico proves that Mike was right about him.
Walt and his neverending butthurt ego couldn't let Jesse have that though. He had to take him away from Fring and put him back on the path that ended with Jesse in a pit and Mike with a bullet in his stomach.
Walt had no humanity by the end of the show and I'm not sure he EVER had any humanity.
Walt's butthurt had nothing to do with it. Walt was in a massive war with Gus and his life was on the line, and Jesse was the key to turning it around because Jesse was close to Gus. Walt couldn't let Jesse have that because Jesse was a judas little cunt that fucked over everyone and then decided to swap sides.
This is the chain of events that lead to Walt not allowing Jesse to leave. You tell me where Walt did anything to 'trap' Jesse in this shit show until Jesse already dug his own grave, and then wanted to abandon Walt after Walt jumped in to save him.
1.) Forced his way back into the meth business by threatening to fuck over Hank, forcing Walt to fire Gale who he had a great working relationship with.
2.) Decided to STEAL Meth from Gus because he felt "Gus wasn't paying them enough"--after Walt told him they were making millions and begged Jesse just to...not be an asshole.
3.) Push his friend to sell the Meth AFTER two Cartel members warning the friend NOT to sell in their territory--he shamed and hounded his friend despite Combo wanting to quit, like a manipulative cunt.
4.) Combo died and Jesse decides he's going to kill those two Cartel members because "they used kids" to lure Combo into a trap. But its just some self righteous excuse because Jesse can't admit he's furious his friend is dead and wants revenge. (And this excuse would go on to kill the kid).
5.) Walt saves Jesse by stopping the hit and brokering a peace deal with Gus. Jesse demands they not use kids. Gus at this point wants Jesse gone so he has them murder the child in order to provoke Jesse so his guys can kill Jesse without Walter losing it, because he's seen Walter is intensely loyal toward Jesse.
6.) Walt rides in and saves Jesse's life, literally. Telling Gus he'll never abandon him and having Jesse kill Gale to cut off Gus's options.
After that point, Walt was in deep shit with Gus. At what point in this chain of events did Walt "manipulate" Jesse? At what point was it not Jesse that fucked over Walt? After this, after he fucks over Walt and exploits Walt's loyalty, Gus sets up a couple scenarios to blow smoke up Jesse's ass, and Jesse abandons Walt. During Gus's manipulations, Walt didn't manipulate Jesse--Walt
literally just told him the truth about how Gus set up the robbery, Walt was the ONLY one ironically NOT manipulating Jesse and being totally honest with him (That's what made the scene so brilliant. Mike and Gus were being kind and supportive, but it was a manipulation to hurt/kill Walt. Walt, meanwhile, was treating Jesse like a peer and being frank and honest with him, NOT manipulating him, so he sounded harsh toward Jesse, and thus the manipulation seemed "better" lol). And Jesse, of course, went with the side willing to manipulate him (After which Walt pretty much understood Jesse is a weak person who will go where the strongest wind is blowing from, which is why at that point he begins actively manipulating Jesse).
And what, you're telling me if you were in Walt's shoes you wouldn't be fucking furious at that? Just because Jesse cries on demand and acts like a buffoon doesn't mean he wasn't a manipulative, conniving person. Jesse gravitated to whatever made him feel good or powerful, destroying everyone around him to do so.
