Catch 22

(Two, Three, Four)
Why would a man who believed in no god
Sacrifice all he had
To kill or be killed in pursuit of a cause
Was the fate that called to him
And you can say he might be crazy
And some can't understand
That a life spent doing less than all you can would be a waste
There's only one way to truly succeed
And it's not through intervention
To influence the minds of the rest of mankind
Will best serve your intentions
