Pillager Patrols & Bad Omen Debuff

Why does killing Pillager Patrol Captains when they enter a village/from inside the village trigger a Raid? There are ways to avoid this happening (having an Iron Golem kill the Captain, setting a trap, etc. where the player doesn't 'directly' kill the Captain), and it feels needlessly punishing to have to kill Patrols in what is essentially self-defense only to have a possible tier V raid occur. Perhaps killing Patrol Captains and their patrols from inside village boundaries could negate the Bad Omen debuff? In addition, Pillager outposts could be changed to have Pillagers spawned from them have a maximum aggro range to avoid people simply luring them to villages and killing them to circumnavigate the Bad Omen debuff. Either way I feel like this is something that could use a fix or change of some kind.
