Uddam Singh was just a normal person(freedom fighter). Yeah something are true that you mentioned about uddham singh like cuting his hair etcc... But he didn't practice sikh religion too much before going to jail. When he was captured and kept in jail, he feared a lot about death for some days, after spending little time in jail he became a true sikh, with 5K's, practicing gurbani a lot in jail. That's why he didn't fear when he was about to be hanged. He was a true sikh after going to jail, not before going to jail. You may got my point. Anyway i didn't see the Udham Singh movie, got to see it.
