If attempting to destroy the WT gives your life a purpose then who is to stop you.

We all need to be careful that we do not become the monsters that we believe we have escaped from.
He who fights with monsters might take care lest he thereby become a monster.
And if you gaze for long into an abyss, the abyss gazes also into you.
Friedrich Nietzsche
Beyond Good and Evil, Aphorism 146
German Philosopher (1844-1900)
As Yoda would say: 'I sense much anger in you'
