Bitterness is a kind of hurt that is poisonous because it causes us to see everything through a victim’s mindset. Victims don’t make great teammates because they target the cause of their hurt for retribution. This can be overt or it can be subtle and passive, but at some point the bitter person is going to make someone as miserable as they are. Bitter people also ruin teams because they tend to rally those that didn’t hurt them to their cause. Bitter victims are easy to spot at this stage because they are working to divide the team.
