While there's no denying, or downplaying all the various instances of legitimate or understandable grief, pain, anguish, torment he's experienced, largely as a result of HIS involvement in that line of work, most, if not all of his coworkers and major show characters went through that x10, esp. considering guys like Mike and Gus, who'd been in the business for decade plus. While these tragedies, and instances are very relevant to Jesse acting like a bytch, the imo, more relevant factor is the fact that he can't handle it. You move crystal, or whatever for 5-10 plus years, and the losses, the agony, the guilt, the regrets will accumulate rapidly. Everyone says 'he's been through hell', yes, but it's how you handle hell that shows the kind of person you are.
