I think he was going for a retrrograde of society where a little kid, all hey remembers is watching jimmy saville on the TV and seeing society has halted he sees saville as a trope to live up to, a real hero (despite them showing he was watching tellytubbies as a kid and saville was well gone from TV by then as only 70s kids knew him, which I assume boyle was)
In reality being that kids age he would have been looking up to shit like TMNT or power rangers not jimmy saville.
I just think boyle thought it would be funny.
