The desire to kill is, after all, an emotion.
Simply put, it’s the intent to end someone’s life. When combined with a martial artist’s energy, it manifests as killing intent.
The deeper the emotion, the stronger the energy. But because it’s just energy, it can ultimately be controlled.
Thankfully.
If someone went around spewing killing intent just because they felt like murdering someone, that would cause no small amount of trouble.
Killing intent is the most distinct energy a martial artist can possess. The higher their cultivation, the more they must learn to restrain it.
If unleashed carelessly, it would be far too easy for others to notice.
Oh my god are we finally coming close to the killing?! I neeeeed it
