Euthanasia or Murder

What is the difference between euthanasia and murder?
A few years ago, I killed my wolfdog. Recently a dog called Malachy was killed.
The clickable title will take you to my thoughts on the difference although the actions taken was the same.

The “Killers” Among Us

A dog was feeding on the body of a dead woman and defending his “prize” aggressively. He was shot dead by the police, who couldn’t wait a minute longer to get to the dead body, it seems.
While we may be quick to blame who looked like the perpetrator of a murder, we may commit an act of violence towards the assumed murderers as they may be either innocent or guilty of a lesser crime.
In quick action for revenge, we may commit murder ourselves.
My kindly looking dogs swiftly, without moment’s hesitation, killed a visiting skunk in their backyard with lightening speed.
Do we, perhaps, all have the inner makings of becoming murderers?
Given the “proper” trigger, in an unfortunate moment, maybe?
These are some of the lessons drawn from this post. As always, the title is clickable.
