Dita - Of course you are right, there are many vile human beings. Also many good ones, I try and remember that.
A woman I know takes in elderly dogs, whose owners have died, or can no longer care for them. Few people want old animals but she always has two or three. One old dog had always lived outside and would only come in for a short time. He liked to sit at the top of the back garden, where he had a good view. So she made him a comfortable kennel up there, to protect him from the rain and left her kitchen door ajar, night and day, even in winter, so he could come in. There's devotion for you.
I asked her if it was safe to leave the door open and she said the dogs might be old but they would have any trespasser's arm off, long before he reached the door
