In Minecraft 1.14.1, when you shoot a pillager leader with a power 5, flame bow, the pillager is knocked down to 5 hit points. The damage from the flame is enough to kill it, but the player does not receive the bad omen effect.
When testing this with a normal power 5 bow, it takes 2 shots to kill the pillager, and gives the player a level of the bad omen effect.
After killing several leaders, you only receive the effect when you do the last hit point of damage.
Summon/find a pillager with the banner.
/give @p bow
/enchant @p power 5
/enchant @p flame
Draw the bow fully back, and then shoot the pillager once. It will be knocked down to 5 health, and then will die from fire damage. The player does not receive the bad omen effect.
