Clearly, he had a problem with authority, regarding his non-response to the repeated requests of the pilot that he unlock the door, a simple matter of flipping the switch. Also, he had to know that he was taking the lives of 149 others along with him, no different, actually, than a lone shooter standing up in a crowded movie theater and unleashing gunfire on the other unsuspecting patrons of that theater, just a different weapon is all.
