"Well he is an assassin who was an experiment of weapon x and he won't shut up".

I'll keep the above for a general idea. However, I don't think I have the patience to go on and on and on all night about what is WRONG with Deadpool.

Deadpool, aka Wade Winston Wilson became a mercenary for Project X after being dishonorably discharged from Army Special Forces.

He botched a job, and his girlfriend was targeted for it but rescued.

He was diagnosed with brain cancer.

Given his condition, he was recruited into the Weapon X program alongside Garrison Kane, Slayback, and Sluggo.

Weapon X's goal, at the time, was regeneration and invulnerability, nigh invincibility.

The program was a bit of a failure. In fact, Deadpool got his name from a group placing bets on who would die first, a "deadpool".

Long story short, he fell in love with Death (personified, of course), was tortured repeatedly, mercy-killed his best friend, had his heart ripped out (literally), staged a jailbreak, got back in the Merc business, was hired to kill Cable, got his butt kicked by X-Force, helped Siryn fight against her uncle and the Juggernaut, fell in love with her (hopelessly, since she's a smoking hot Scot and he's a walking scab), AND SO ON AND SO FORTH.
