Wade Wilson (Earth-4126)

"Guns don't kill people. I kill people. And I'm betting you do too."

-Wade Wilson

Childhood
Wade's father was a police officer and his mother was a nurse. Every day after school Wade watched his little sister Ally until his parents would get home. Wade's friend, Cletus Kasady, would come over a lot, and he thought Ally was a huge pain. Cletus didn't tell Wade how he was abused at home, and he was eventually driven insane. One day when Wade was at school, Cletus snuck into his house and used Wade's mother's nurse tools to kill Ally in her sleep. Wade got home just in time to catch Cletus in the act. He grabbed the nurse tools and used them to murder Cletus. His mind snapped in horror of what he had just done, and he decided to hide in the basement.

Fall Into Insanity
When his parents got home, they couldn't find Wade. They looked in the basement and, out of fright, he attacked them and slaughtered both of them using his mother's dissecting tools.
