Obviously, McTear is sick; therefore, I don’t want to dwell on his actions but rather on how to help women avoid such men and help men recognize when they need to get help—before they shed innocent blood.
So, women, how would you know if the person you’re dating is capable of this sort of violence?
Look for control issues. If he always has to pick where you go for a date, where you sit at the movies, orders your food without asking what you want or needs to know where you are and who you are with every second of the day—step back, he’s crazy!
Observe what he focuses on. Psychopaths can be very obsessive-compulsive on the smallest things. If he freaks out when you move a knick-knack on his mantle or fold a towel the wrong way, you may be in for a scary ride.
Watch for attempts to isolate you. Psychopaths work best once they have you isolated from family, friends and anyone who can point out what a kook you’re involved with. Sometimes, they start by needing to be with you every moment, leaving you no time for others. He’ll continue by curtailing your phone calls. He’ll conclude by taking you to isolated places, like his "romantic" trailer up in the mountains, where you can’t get away.
Beware of jealousy. If he becomes insanely jealous and enraged when you talk to the waiter, your friends, or even your brother, get out of the relationship.
Finally, take this tip from Dovescorner, Psychiatric Nurse at a major hospital and good friend. Look for change! Sudden and not typical "he is finally coming around" change in situations. Bipolar people usually do this before just before committing suicide.
Guys, how would you know if you’re crazy?
If, like this fellow, you’re caught up in a lifestyle that only allows resolution of problems through violence (whether physical, emotional, verbal, or whatever), you don’t respect human life, you don’t mind taking a human life, or you don’t respect your own—and all of your "friends" act and react the same way, you are crazy. Get help; now!
It's as simple as that.
