Too many times I hear people comment on people with splitting behaviors something along the lines: “But they are total angels when they don't split”, or “I know deep down they are kind and empathetic”.
Well, when someone denies aggression ever exists at all, of course what you have left is an overly helpful person and all other good traits, at least in public. But the thing about being emotionally dishonest regularly is you never know when the dark side comes and goes. You can't have just the self-sacrificing person for your benefit. Because more often than not, they find loopholes along the way to justify the cruelty when it's necessary. It's kind of a whole package deal.
