The end justifies the means

I was having tcss session with Andre. E & Matthew. S after the econs paper for a good 4 hours. ( That extended to an another 3hours over a spread of dinner+ facebook chat)

Then they mentioned this phrase that sets me into deep thoughts mode.
 It is 'The end justifies the means' ,originating from Niccolo Machiavelli's book "The Prince"
For those that doesn't understand the phrase ( like yours truly),

The phrase the end justifies the means refers to the morality of an action. It means that the morality of an action is based solely on the outcome of that action and not on the action itself.
Example: Telling a lie that has no negative effect on anyone, and saves someone grief, is good. Killing someone to save others may also be morally justifiable.

In my opinion, I think that anybody who lives by the idea of this phrase will be a quite corrupted and selfish person. It's like as long as you get what you want, you don't care about how gruesome the method you used are. In the end you still feel like you accomplished something honorable etc. after the goal is reached just because of " THE END JUSTIFIES THE MEANS" theory. 

Le sigh, idk what am I talking about right now, too shagged.
Alright guys. GOODNIGHT.
