All we saw was that he was a garbage man now and likes music. Just because someone went through something crazy doesn't mean they will never work a day in their life lol
Because the movie already heightens the toys to being alive the punishment is probably more representative of the emotions and desires of vengeance his sister had.
I know I'm being pedantic, but that's the word used in the video and that's the slang term, specifically "bike", probably because it sounds more punchy.
To be even more pedantic, the guy is Italian and that is relevant to the character. In Italy we say "if my grandmother had wheels she would be a wheelbarrow". He pauses a moment before saying the joke, probably because he didn't remember the word wheelbarrow and went for bike instead.
I took apart my toys and made new toys out of them all the time when I was a kid and several decades later, I appear to be a normal member of society without having committed a single murder.
My friend's sister took a permanent marker and wrote her name and drew a stick figure on his G.I. Joe Terror Drome toy (one of the most expensive in the line at the time). No one hoped she would be haunted by Cobra action figures for her crime.
