Why did Flight 17 travel over an active war zone

While people are busy playing a gruesome game of 'whodunit' in the Malaysian Flight 17 shootdown over Ukraine, there's another aspect suddenly getting urgent attention: Why did the plane even fly over that area to begin with?

We know this from the UK DAILY MAIL, reporting information on the air track in recent prints:
The pilot of MH17 radioed that he 'felt uncomfortable' about the route he was flying while over Ukraine and fatally altered his course to hostile territory, according to an expert.
Dr Igor Sutyagin, Research Fellow in Russian Studies from the Royal United Services Institute, believes that MH17 was shot down by rebels based in the 3rd District of Torez, in eastern Ukraine, after mistaking his plane for a government military transport aircraft.
He told MailOnline that information had been leaked from a source he was unwilling to name that the pilot of MH17 'felt bad' about his course over Ukrainian airspace, so changed direction.
