When D does the opposite of whatever Boolean value
that H returns then D is contradicting H.
D contradicting H is not the same thing as H contradicting itself.
D is the problem.
Not H.
OK great this is close enough. When D does the opposite of
whatever H says then it is D that makes this question:
Does your input halt on its input? have no correct return
value from H. So D derives the incorrect question for H.
An incorrect question is any question that lacks a correct
answer because there is something wrong with the question.
There really is self-contradiction in there somewhere
because it has the same pattern as the Liar Paradox.
A self contradictory yes/no question is any question that
contradicts both answers.
A contradictory question differs from a self-contradictory
question find an integer N such that N > 5 and N < 2.
