>Samson
Samson is great. The last thing he does with his life is a murder-suicide, because he wants revenge for having his eyes poked out (which probably isn't the worst reason really).
He uses his superpowers one final time to collapse the temple he was being held in, where everyone had brought their families to watch him perform, killing himself and everyone their in the process. It is said that in death, he killed more people than he had his entire life... And he was the guy who beat to death an entire army with just the jawbone of an ass!
He was basically a drunken, glory seeking asshole, who used his powers for whatever he felt just because he could.
A his wedding, he gave the groomsmen an unsolvable riddle, and said if they can solve it he'll give them all new clothes. So the they threaten his wife, and get her to ask him for the answer to the riddle.
Samson tells her and she tells them, but he knows they cheated, so he goes out and kills a bunch of other Philistines, steals their clothes and gives them to groomsman.
Samson is still pissed off about them cheating, so he abandons the wedding and goes to stay at his dad's house. Later he goes to his father-in-law's house who tells him that Samson is such an angry dick who abandoned his wife on their wedding night that he gave her to another man and they are now married.
He then tells Samson the he'll let him marry one of her sisters instead, but this pisses Samson again. So he goes out and catches 300 foxes and ties them together, lights them on fire and sends them into town where they burn down all the Philistines crops.
The Philistines are upset, and they blame Samson's would-be father-in-law for giving his wife to another man, and so they murder him, the wife and husbanded, by lighting their houses on fire. This pisses off Samson more so goes on a murder spree, killing everyone in town.
That's basically his life, causing destruction and being really pissed off. He's the Hulk, basically.
