Cold blooded mass murder
Yep - this is more than simple suicide, its terrorism in my book. Selfish little creep. Slightly tinfoil hat: I still wouldn’t be surprised if he was writing his own sick notes - tearing up the ones that didn’t look quite right (eventually found by the investigators), just for cover while he “researched and trained” for his suicide.
Lubitz was exactly that... a cold-blooded mass murderer...and worse than most because the people's lifes he took had no options to escape the confines of where he trapped them. He had a choice...the people had none.
