Edmund Burke. The actual quote is: "The only thing necessary for the triumph [of evil] is for good men to do nothing."Addendum:
The "actual quote" cannot be found. While it is attributed to Burke, there is not evidence that he ever actually spoke or wrote it, and Burke was a prolific writer and speaker.
There have been countless attempts to tie it to a specific piece of writing, and some of these are laudable. One of the most likely sources of this particular bit of wisdom could be: When bad men combine, the good must associate; else they will fall one by one, an unpitied sacrifice in a contemptible struggle. It was born in Burke's speech of 23 April 1770, "Thoughts on the Cause of the Present Discontents," delivered to the House of Commons.
The quote as it is in the question appears in at least eleven different permutations on the internet:
These more commonly worded permutations of Burke's message survive, perhaps more because they appeal to the modern ear. Call it poetic license, but Burke's words live on, they just look a little different.

he did nothing good he was a total evil madmanThe good things he may have done were outweighed by the evil he did in the effort to create an Aryan nation.
Evil is anything that kills, steals, destroys, deceives & takes advantage of weaker people. Good is treating all creatures as good as you would want someone to treat you
It is simple: evil is allowed to happen when good people do NOTHING.
