Is "who" used correctly in the sentence "Or he's a supernatural demon designed to torture people, who got offered his dream job"? [duplicate]

Is is a rule that relative clauses should be added right after the antecedent(the noun relative pronouns refer to)? What if it is confusing?

For example:

"I went for a spin with a handsome boy last night."

"The handsome boy went out with my friend."

"I went for a spin with a handsome boy who went out with my friend last night ."

"I went for a spin with a handsome boy last night who went out with my friend."

There is some confusion here about how relative clauses work. See McCawley's SPHE for a good description. Here are some notes:

The antecedent of the relative pronoun in a restrictive relative clause is the entire noun phrase within which the relative clause occurs (not what the relative clause modifies). (In the preceding sentence, the antecedent of "which" is the noun phrase "the entire noun phrase within which the relative clause occurs".)

A restrictive relative clause modifies an N-bar, not a noun. (So in sumelic's example in the comment, the relative clause modifies the N-bar "someone strong".)

Restrictive relative clauses can sometimes be extraposed to the end of the verb phrase, as in "A man appeared who had a sinister red beard."

A relative clause does not in general begin with a relative pronoun, but rather with a relative expression within which a relative pronoun occurs (as for instance this very relative clause, which begins with "within which").
