Yea, they can be outside, don't mind them there. Snakes however have no reason what so ever to exist on this earth.
I don't mind if they are endangered, must die or I must go somewhere else if I see one.
The venomous one we have is not that bad if you get treatment early.
Basically only deadly for children, old people and sick people.
But even our non-venomous creeps the hell out of me.
Just writing about it sends unpleasant shivers down my spine.
