The flaw here is that girlfriend =/= waifu, but I get your point.
As well I am assuming that this man could've been an actual schizo, since I do not think any waifufag of any kind, no matter what are his physical conditions in all their terms, (e.g. psychological, race, etc.) would do this kind of thing.
Also the man Armstrong could have just been fucking around with him and most likely a sightly bully for shits and giggles, but killing somebody for that is definitely not okay and anything related to murder.
Of course, there could be that one anon who will kill his own parents if they ever dared to burn their newly ordered daki that they payed 500 bucks, but one should be able to be smart enough to do such thing, since taking those type of waifufags whom doesn't have anything physical thing related to their waifu, a love for someone should not be physical at all.
But then, who am I to judge?
