"hatred"
This is a mistranslation:
Dvesha (Sanskrit: द्वेष, IAST: dveṣa; Pali: 𑀤𑁄𑀲, romanized: dosa; Tibetan: zhe sdang) is a Buddhist and Hindu term that is translated as "hate, aversion".[1][2][3]
Aversion is a better translation. Aversion motivates pushing away (making it someone else's problem) whereas hatred motivates proactively chasing down (for the sake of destroying). It is therefore aversion which is selfish, and hatred which is selfless. Given that the whole point of Buddhism is to remove the self/non-self distinction, it is aversion which is poisonous to this pursuit, whereas hatred is consistent with it.
