are you a vulcan or something?
For my own sake and that of others, SOME respect for their wellbeing is necessary. Beyond legal requirements, I have little-to-no morals and no affection for other humans, so I try and do the legal minimum to not hurt them.
And what makes you think that the law has anything whatsoever to do with protecting anyone from any kind of hurt? That's 20th century stupid thinking. The law is a weapon of the propertied classes to impose social and economic conditions on the unwilling.
"Ah, those endless forests, and their horror-haunted gloom! For what eternities have I wandered through them, a timid, hunted creature, starting at the least sound, frightened of my own shadow, keyed-up, ever alert and vigilant, ready on the instant to dash away in mad flight for my life. For I was the prey of all manner of fierce life that dwelt in the forest, and it was in ecstasies of fear that I fled before the hunting monsters."
