The only surprising thing about this to me it that it doesn't happen more often. With almost no Church guidance, all sorts of lies being peddled, even from the Alex Jones Troof Movement ( as opposed to a Truth Movement ) and a bureaucratic state whose rules are arbitrary and make no sense -- notice college tuition going up and usury through the roof at a time when the economy is going down and is NOT going to recover -- the devil is obviously trying to drive people stark raving insane and create chaos.
You would expect events like this on a daily basis, considering how absolutely Alice in Wonderland MAD the world has become during the Apostasy. However, another feature of the modern world is that it breeds docility and self-hatred, which is why manifestations of misery are not usually this spectacular but are usually confined to someone killing his family and himself, rather than picking some kind of target that he can blame his woes on.
I'm sure people will judge him for being against the "Catholic Church." But ( 1 ) It isn't the Catholic Church and ( 2 ) If it were, it would only be imperfect in its members. Not being Catholic, he didn't understand ( 2 ), not that that will save him. And almost no one, including those attempting to be Catholic, understand ( 1 ).
His action, from his perspective, is not excusable but is understandable, when you consider the avalanche of lies that besiege modern man with absolutely no let up. Unfortunately for him he was absorbed by the lies until his last breath. Though he claims to be disillusioned about America, actually his final act was gruesomely idealistic-patriotic, since he thinks the IRS is ruining the country which was really ruined as soon as its Constitution was drafted. I have long been expecting some kind of "patriot" revolt, a revolt based on the wrong premises entirely, which is that it is anti-Christ America rather than the Church that is worth fighting for. I guess this was a one-man version of that oft-proposed revolt.
