Yeah, but I think the killing of the professor, et al was ancillary to his real issue....HIS weapons were the ones doing the killing. HE was responsible for the deaths.
By that logic, when bin Laden had his men fly planes into the Twin Towers and Pentagon, Boeing was responsible for the deaths.
But, anyway, I took his decision, and the rest of the film seems to bear this intepretation out, that he was upset by the fact that his weapons were falling into the wrong hands, or could do so, not that he was against violence per se.
If anything, it stretched credibility more to interpret the plot as if he was originally unaware that his weapons killed people. They WERE weapons, after all.
