My original opinion is that human logic has something evil to it and that I don not fully trust it. If you don't like the word evil for historic reasons call it destructive. — FalseIdentity
If you mean by "logic" "problem solving" then I don't see why it's evil or bad. Though people can use it in a bad way. I have had discussions with physicists who merely use their ability to solve problems to show of their ability to solve problems merely to show of and feeling superior to others. They are in general quite dumb people with no real interest in physics, talk like parrots, and behave like robots. They don't have too much imagination and have found their place in the system. Somehow I feel evil in these kind of physicists.
From child on we are trained in problem solving and there are all kinds of logical formal systems (math, proposition logic, or whatever abstract problem solving strategy) let loose to enter the minds of the sweet child in time. From being playful, colorful, spontaneous human beings they are turned into serious, grey, programmed creatures. Nothing wrong with being like that, but it's forced upon us. Children are
obliged to go to school. Science embraces problem-solving and knowledge-gathering. Ad nauseam. In the process of logic, destruction takes place in the name of science. Logic can have destructive outcomes if relentlessly applied or forced upon us by politics. This eagerness to know and investigate is a nice human quality. Like problem solving. It has always been strange in my eyes that for examining the smallest the biggest experimental equipment ever was built (luckily the 6-billion SSC was called of, although Lederman and the likes of course hammered on its "importance" while in fact it's not needed at all to look deeper because you can imagine the subject matter too, without disturbing the world or measuring whatever). How many Nature was destroyed because of this? A considerable piece, including underground. A formal and abstract system of logic can be applied to every worldview or culture besides the scientific view (constricting the sciences in a strangling way though, like sir Popper and the likes try(tried)) and forcing it, together with science itself, upon these cultures has been performed very efficiently and with power given by science-based weapons. It's the never-ending tendency of science to solve problems and investigate which causes Natural destruction. On top of this is the application in economy. Also there inflation (like in the sciences!) rules suppreme. With all destructive consequences (besides the destruction involved in the knowledge-gathering an Sich). Logic can be nice. So can be science. It can do evil, destruct, and constrict, like the so-called scientific method, and even the most logic formal system (mathematics) do (though in science the last is used in almost every area of it). It can do harm to Nature and other cultures. The people using and applying it, that is. Logic and science are human enterprises, with a base in the old Greek philosophers like Xenophanes (from who the now common western belief stems that there can only be one objective reality, which he expressed as his only super monster-god, like the one in Christianity or Islam, from which many science developed too; as opposed to the many ones on the Olympos), Plato, or Aristotle. What a difference between them and their present day descendents though! Like the difference between a sweet-smelling colored flower in the rain forrest and a plastic dull one in a designer vase (the last brings to mind, I don't know why, that despite all individuality of present day, there is a kind of uniformity in mankind as humanity has never faced before).
So. Is logic evil? Is it destructive? The last yes. It destroys the outer physical world as well as the full inner potential. Now, the destruction of the natural world isn't evil necessarily. But what about all kinds of experiments done on living creatures to gather knowledge in the name of science (and usually the link to medicin is made to justify it) and problem-solving in relation to it? What about the logic of Popper, Kuhn, Radder, Lakatos, who all try to rationalize, methodize, formalize, or standarize, the sciences, try to put it in an abstract formal system? Now math does that too but it's a part of many sciences (though it can be quite constricting to them too). Don't they (wannabe scientists?) restrict the sciences and their progress? Don't they destroy the process of evolving science if scientists would conform to their measures? I think this is so.
Of course logic can't be bad or evil. Neither good or halo-wearing. It's very restrictive though. Strangling even. It kills human qualities present besides problem-solving or non-logical qualities involved in that "solving". It causes misery in nature (which we try to "solve" by logic and science that caused it in the first place!).
Can you give an example of the destructive power of logic? What do you mean, by the way, by "stolen life energy" and "donated energy"? Brain electric potentials and external voltage supplies?
