All this may be compared to a sheep/wolf/sheepdog analogy
Most people are sheep. They are kind, gentle, productive creatures who only hurt one another by accident. They are peace loving, avoid violence, and it takes a lot to provoke them into violence. They may fight back if directly attacked but they are oblivious to the predators that hunt them. Even if they do fight back, they lack the skills or the will that it takes to fight effectively. They are at the mercy of predators.
Surrounding these sheep are wolves, fierce predators that hunt, attack, and feed on the helpless sheep. Sometimes there may even be wolves in sheep’s clothing that may seem to be a part of the flock, but at the first opportunity, they will kill and eat sheep. After all, they are wolves, not sheep.
The only thing that protects sheep from wolves is the sheepdogs. The sheepdogs help keep the sheep organized and content, and when needed, they confront the wolves, run them off, and if necessary, fight them to the death. Sheep tolerate the sheepdogs because they need them for protection, but they do not associate with the sheepdogs. The sheepdogs do not care if they are not accepted by the sheep; just continue to do their duty, most times unnoticed.
If you have no capacity for violence and feel compassion for others, then you are a sheep. If you have a capacity for violence and feel no compassion for others, you are a wolf. If you have a capacity for violence and feel compassion for others, you are a sheepdog. Sheepdogs are the warriors of the pastures.
