Yea you're right even that group he was with said "he was crazy." He suicided after killing them, very sad the highly decorated officer who came was also killed by this .. Terrorist.<quoted text>
From reading more about this guy, I don't think it mattered if it were Sikhs or Muslims or Hindus.
He undoubtedly knew that he was attacking a Sikh temple, he just did not care.
He saw turbans, and went into action.
Sounds like he was damaged goods from the military, probably had all sorts of depression and mental issues.
