WILLFUL incompetence IS malicious, as is incompetence resulting from willful stupidity, a common trait in those who want to control others’ lives. (No matter how “intelligent” someone is, choosing to do stupid, harmful things just because one wants to–for whatever reason–is just plain evil.)
“Smart” people who choose to behave like morons also seem to be “the universe’s” way of saying there are holes in Darwin’s (and his worshipers’) theoretical musings. . . and the universe (via plain old cause and effect) is perfectly happy to fill those holes with self-made morons’ disasters.
