that might not fix things once and for all
it may just set up "reciprocal animosity"

If you cannot "kill" energy you must transform it
turning an enemy into an allie is the best way to defeat an opponent.

"do not combat evil directly,
you'll become entangled and actually give your power away
instead make energetic strides for the good."

when in life you meet a foe, bless them, praise them and let them go"
