Set fire

Which version is correct:

  1. He sets fire to himself;
  2. He sets himself on fire;
  3. He sets fire to him;
  4. He sets him on fire ?

Or just

  1. He burns himself

Thanks a lot.

Unless two people are involved, only these are right:

  1. He sets fire to himself
  2. He sets himself on fire
  3. He burns himself-- This one, however, doesn’t suggest the same meaning; it suggests an unfortunate incident with a frying pan.

The first one is right.

set fire to themselves

Where did those other suicides come from, Gary? They’re not in the original sentences.
