See you're just saying nonsensical jibber jabber without putting a context to it which tells me you're just playing devil's advocate for no reason.
The story as it was related was designed to show that Al's imprisonment wasn't all fun and games...it usually was depicted that way but that story showed there was another side to Wade and Al's relationship...Wade would kill to keep Al with him. The reason she related the story was she was worried how Deadpool would react to Wade's friend Weasel's attempts to socialize with her.
The dude he killed's motives were never a factor. Wade killed the guy to victimize Al and keep her dependent on himself. As her captor he was trying to break her spirit to keep her from escaping.
No, I just disagree. If he were trying to break her spirit it was only for her own good. Her life very much depended on her being completely dependent on Wade.
