Use pronouns ending in "self" only when the pronoun refers to the subject:

He brings shame on himself.

-- "He" is the subject; "himself" refers to "he."

His deeds bring shame on him.

-- "Deeds" is the subject.

His generosity speaks for itself.

-- "Generosity" is the subject; "itself" refers to "generosity."

Don't use the "self" form of pronouns after a comparison.
