Is it the attitude that one has when choosing a course of action that decides your dudeness or is it the action it's self.
For instance William Shakespeare said "first kill all the lawyers" in Henry VI
Quote
JACK CADE. Valiant I am.
SMITH [aside]. A must needs; for beggary is valiant.
JACK CADE. I am able to endure much.
DICK [aside]. No question of that; for I have seen him whipp'd three market-days together.
JACK CADE. I fear neither sword nor fire.
SMITH [aside]. He need not fear the sword; for his coat is of proof.
DICK [aside]. But methinks he should stand in fear of fire, being burnt i' th'hand for stealing of sheep.
JACK CADE. Be brave, then; for your captain is brave, and vows reformation. There shall be in England seven half-penny loaves sold for a penny: the three-hoop'd pot shall have ten hoops; and I will make it felony to drink small beer: all the realm shall be in common; and in Cheapside shall my palfrey go to grass: and when I am king,- as king I will be,-
ALL. God save your majesty!
JACK CADE. I thank you, good people:- there shall be no money; all shall eat and drink on my score; and I will apparel them all in one livery, that they may agree like brothers, and worship me their lord.
DICK. The first thing we do, let's kill all the lawyers.
So now lets assume that Dick (not actually a Dick) and his friend jack went off with joy in their heart rounding up the barristers and offing them. One could make the case that they were being rather Zen. I mean the "and I will make it felony to drink small beer" quote alone makes this guy a major dude in my opinion.
Just saying...
If you meet the Buddha, kill the Buddha.
Was he a lawyer?
