The way you do things matters as much as what you’re trying to do. From Martin Luther King:

One of the great philosophical debates of history has been over the whole question of means and ends. And there have always been those who argued that the end justifies the means, that the means really aren’t important. The important thing is to get to the end, you see.

So, if you’re seeking to develop a just society, they say, the important thing is to get there, and the means are really unimportant; any means will do so long as they get you there? they may be violent, they may be untruthful means; they may even be unjust means to a just end. There have been those who have argued this throughout history. But we will never have peace in the world until men everywhere recognize that ends are not cut off from means, because the means represent the ideal in the making, and the end in process, and ultimately you can’t reach good ends through evil means, because the means represent the seed and the end represents the tree.

–Martin Luther King, Christmas Sermon, 1967
