Voluntarily to participate in voting; is to invite evil into one's heart

Voting, as a method for arriving at binding decisions; is clearly evil in itself and tends to corrupt participating individuals - as becomes obvious to those (but there are few such!) who shake-off the propaganda and ask the right questions. 

Furthermore; the extent to which voting corrupts its participants has increased, as the range of options to be voted-upon have all become evil-aligned: net-evil in their nature. 
In other words, voting is more extremely evil when the voter is choosing between evils; and is casting his lot for (what he tries to discern as) the lesser of acknowledged evils. 
Lesser or not; a vote for evil is a vote for evil.  

In different words: voting is not so bad when a vote can be (and is) cast for some positive net-good (e.g. for some good-affiliated person, party, policy). But voting becomes extremely corrupting when all possible options are net-evil, evil-affiliated... When all choices are actually motivated against God, divine creation, Jesus Christ... 
Then all voters are actually voting for evil.  

Evil, because the process and act of voluntary voting is (passively expressed) an act of consent; also (actively conceptualized) itself an action in support. 
When evil is voted for - including a lesser evil - then this is to invite evil into one's heart. And that is the only way that evil can enter one's heart. 
We cannot be made-evil purely from external influence; evil must (like a vampire) be invited-within. 

And surely the actual corruption from voting is obvious to anyone who is good-affiliated and stands outwith the processes of voting? Such as political elections; but also any other situation when would-be binding-in-advance decisions are made by some mathematical counting procedure. How could anyone regard such a procedure as intrinsically virtuous? 

Ultimately, voting has come to dominate societies of the modern world, at every level power is exercised; exactly because when people voluntarily participate mentally in the business of voting, they are choosing to take the side of evil in the spiritual war of this world. 
(And the spiritual war is what matters most to those with greatest power.) 
By voting; Men are choosing to corrupt themselves, by inviting evil into their hearts - again and again. By defending voting, they are doubling-down on evil: actively repelling good.  
Furthermore, as the matters voted-upon have been made all evil, and more evil; such corruption has accelerated and become more extreme.
