The end justifies the means

Doesn't matter what you do as long as the outcome is your wished result. This quote is not always true. Because it can be covered as both good and bad things. the final outcome becomes the reflection of your earlier acitons. For example, if the goal your trying to achieve are negative, you should not try to approach it that way. This qoute does make sense, and is true, but it can be considered as both positive and negative.
The person who wrote this quote was Machiavelli,  a man that was very negative about liufe, and believed in fear and hate. Based upon this fact we can say that this qoute cannot be placed as a ALL- situation quote.
