From his screed on Infowars:

I am broken hearted tho to see people so pacified by materealism and obsession with hollywood stars. It is our duty as American citizens to stand against tyranny. To stand against corruption at all levels. How did this happen? That patriots like me could be resting under the boot of tyrants, and as i plead for help from my fellow americans they just walk on by. All the while thinking, at least its not happening to me. Yet, the sad thing is, it is happening to them. So, do I kill cops and make a stand when they come to get me? I would prefer to die than sit in their jail, when I have done nothing to hurt anyone.

That explains the suicide pact with abundant clarity.
