Calling him mocking names like Tomato Andy qualifies as bullying. That will be where the blame heads.
Reports in German media suggested that Lubitz had suffered from depression in the past, and that his employer would have been aware of his history.
Germany’s Bild newspaper reported on Friday that Lubitz had suffered from depression during a period when he broke off his training six years ago. It said he spent over a year in psychiatric treatment.
Lufthansa, parent company of Germanwings, has acknowledged that Lubitz had broken off his training in 2009 but says there was nothing in the pilot’s background to suggest he was a risk.

No doubt, totally justifiable action crashing a airplane if bullying was involved !
I can see the talking heads now, lamenting not the victims, but the bullied Tomato Andy.
