I agree with the vicousness of the animals needing to be toned down a bit as I keep joking about it.
Animals as a problem: Certain type of animals would eat food on the ground
Only when animals can eat can visible eat they be domesticated.
But even before domestication a drag function is needed so instead of killing them all at least we could lock them up in a building. {And use this as a means of execution}

I saw that animals went onto the road. They should shomehow feel more comfoatable staying there. There's less people and the assumption could be made that they can forage while on the road maybe. This would bring hunting into play.
