Though his death wasn’t especially grotesque, the disposal of his corpse was completely disgusting. Walt leaves Jesse to dissolve the body in a chemical bath. However, Jesse cut corners and decided to do this in his own bathtub.

He was tough, loyal, and learned how to cook Walt’s meth recipe. It’s everything Gus ever wanted. However, he also foolishly allowed himself to be spotted at a murder scene. This went over terribly with the boss, who cut Victor’s throat with a box cutter while the rest of the staff watched in horror.
