As per 亞# (downward pressure) + 心 heart/emotions → hatred/resentment induced by being pressured → *evil*; *wicked*; *bad*; *hatred* → *wrong* (← bad attitude, answer etc.). There is a possibility that the graphically similar ?(one's true nature) described in 德 has influenced the meanings of 惡 in a reverse, negative sense.
