Suppose hypothetically someone like Adolf Hitler had converted to Christianity?

and got true faith in Jesus Christ just before his death and confessed his many sins (and suppose he did not commit suicide), would/could that evil-doer be admitted into heaven? I personally would volunteer to be sent to hell if that were to happen, since I would not want to be in heaven, where I would be expected to ociate with such a person as Hitler. This is just a hypothetical. But am I wrong in feeling that way?
