Little deer, RIP

I have two questions.

1. If there is a poeple who is knocked down by a car, and the knees are broken. What would you do? To save him or to kill him?

2. If there is a deer who is knocked down by a car, and the knees are broken. What would you do? To save it or to kill it?

If people saw a man who was knocked down by a car and got injured, I think people would call 911, wait the cops arrive and send the patient to the hospital. So the answer would probably is "to save him." Right?

However, in this country, if poeple saw a dear which was knocked down by a car and get injured, people would also call 911 and wait for the cops arrive. Instead of save the deer, the cops would help the deer die sooner.

Howcome?

I think it should be respected no matter it is the life from a human or from a deer. However, why the human would be saved and the deer would be shot? Why the human has the right to kill other animals? Are we just choose a easier way for ourselves to survive, so that we can disregard the lives of other animals? May be I am just naive.

Sitting by the window and looking at the deer from the oppoisite side of the traffic from my house. I am sad. Little deer, I hope that we are helping you to get away from the pain sooner. I hope you sleep well. Rest in peace.
