The first segment does not show Lawrence being raped as in the original film. Simply being whipped does not provoke such a desire to kill as that of being dehumanised, or feminised, by anal abuse.

When I first watched this film back in the 60's I was on the side of the noble Arab against the brutal Turk. Now that I'm an adult with a knowledge of history I find this film inaccurate, manipulative and offensive.  There is no such thing as a noble Arab unless they  absent themselves from the degeneracy of the ideology of Islam. Killing the oppressive representatives of the Ottoman Empire freed them not one jot.

I could be mistaken, but I don't think the original film actually showed the rape.  I think it was implied, which was shocking enough in the 1960's (and today).

It was also implied, but not stated, in Lawrence's autobiographical "Seven Pillars of Wisdom".

Of course neither the penetration nor the touching of the victim's and the perpetrator's bodies were shown, but the Turkish officer undid his belt and approached Lawrence from behind. The next we see is the Turkish guard holding the prisoner's arms grinning maniacally.   There is no sound of a whip or cane as the film cuts to the shocked grimace of Lawrence. He wasn't having his feet tickled.

It would not be simply a rape for sexual pleasure but a means to make clear to the victim his inferior status.   Lawrence's enjoyment in killing Turks, expressed in the film during an interview with General Allenby and why he asked to be posted elsewhere away from this temptation, most likely had it's force due to his humiliation.
