Plenty of nice old ladies get mugged and killed every day - what's your point, that a nice old lady lives a better live than a drug dealer, or that military and police just aren't necessary if you think good thoughts?
What do you mean what's my point? I already made it. I didn't say any little old lady thank you. I'll repeat it just for you.
Kind people are fiercely protected by those who know them. This kind of adds a little extra to trying to compare animals to humans using darwinian theory.
The sword I use is the sword of kindness. I'll leave you to work that one out.
