The passage allowing "innocent" or "oblivious" actions with evil result conflicts directly with the definition of "malice". Someone like the elderly sisters in Arsenic and Old Lace, who poison old men out of a twisted sense of kindness are anything but malicious. Contrast them with Dolores Umbridge from Harry Potter who pastes a sweetly simpering face on top of explicitly evil intent, and who I think embodies what the trope name seems to be about.
We either need to exclude "non-malicious" examples from the definition, or use a word other than "Malice" in the trope name, because right now the trope is a mass of self-contradiction.
