Breaking Beds/Killing Villagers During Raids, Ends Raid And Gives Bad Omen

During a raid, if you destroy all the beds in the village being raided, the raid will stop(of course) however, you will also receive another hour and a half of bad omen.

This also happens when all villagers in the village die, raids stops, and you get more bad omen.
This partly seems intentional, but also seems like a weird thing to have happen.

Tldr, not fully sure if this is a bug or not
