I had reason to mention before that Indian philosophers place more importance on motives than on action. The thing is you can hardly ever understand someone else's motives. You can only see him act. So, yeah, if the chap pockets your money or stabs you in the back, you will automatically classify him as untrustworthy. You will not try to psychoanalyse him and determine his motives before hating on him. The thing is (a) not everything is as clear as that. Sometimes, understanding actions depends on context, no? AND why so? Because context determines motives; and (b) What about YOUR own actions? Do you hide behind the fact that your actions were virtues - telling the truth, doing your duty etc - when your motives were false? Pulling down your competitors, following illegal orders for raises and promotions etc? YOU do not claim that you do not know your own motives, do you?
AND Tiru says this...
Achchame keezhgaladhu aacharam echcham avaavundael undaam siridhu - Tirukkural
The base man's virtuous actions are grounded in fear; what remains will be based on greed - Loose translation
So, Tiru holds that an evil man behaves in a virtuous manner only out of fear. Fear of punishment, fear of social opprobium, fear of loss and so on. If that fear does not exist, then his virtues would vanish. Basically, all of fear starts from the fear of getting caught. If you do not get caught, none of the other things can materialise, no? So, then, see the behavior of people when they do not fear getting caught and you can understand how virtuous they really are. How do they behave in mobs? Do they loot in times of disaster? Virtue which exists when there is no fear of getting caught and no material consequences to committing vice...THAT is true virtue.
Tiru also holds that there may be SOME virtuous actions committed by the evil man even when fear does not propel him. AND those actions will be based on greed. Where the acts of virtue will beget him more benefits than the costs. The charity of those who do it only for power in Society, say. The middlemen who help you with what you need from Govt...for a price. And so on.
In fact, most men seem to balance fear and greed. The costs that are inherent in getting caught versus the benefits. THAT calculus runs Society all the time...or so it seems.
Actions, therefore, are no true guide to identify virtuous people. Motives are.
But...does anyone really want virtuous people these days? I mean, between a base man who can get you your license to open a school and a virtuous man who will ask you to do the honest thing and have you run from pillar to post...
Maybe Tiru's times were way different after all.
