It's there a digital source? A URL?

That's a terrible source. It wants me to use the "Funny Ap" or Google Chrome.
Where did the photo come from?
The original quote came from LTC David Grossman's book "On Killing" and I first came across it in this YouTube video https://youtu.be/Awd4LW9PQSQ When I went to look for the image, the only place I found it was in this link's location https://images.app.goo.gl/3Mq54BzBcMKDV4rb7
If you find information within a book or periodical you will want to cite the page, book and author, even the ISB number. This allows others to verify the information.
We have become so easily spun up on simple propaganda that sceptics among us now won't even research anything. It's all based on reputation and what the media who themselves never research anymore, anything or they will deliberately obfuscate the truth in order to defame a personality and his work. Robert F. Kennedy, Jr. it's a great example of this
We need solid references to the authority (author) of information, ideas and conclusions to give credit, investigate further or see that the source, himself, is compromised and may be leading in misdirection for the purpose of fostering ignorance.
It's no so much authoritarian worship (Fiat) but it is understanding who the author is and what he is trying to communicate. Running with an idea leads to speculation and that is fine if you are totally in the dark but the habit of citing sources will lead to the ability to assess your critics as incapable of critical thinking and you can dismiss them easily whereas a good critic may lead to insight for you and him with investigation of sources.
I always name or link to sources, however in this instance it was a meme-type image which was self referencing and explanatory.
Did you not see the line, "LTC David Grossman in his book On Killing", at the base of the image?
I figured that was enough source because we all know how to do a Google search for "LTC David Grossman in his book On Killing".
All I did was search that sentence online to find the image for you, plus it's easy to then search for the book as well.
I do agree with your statement and its sentiment.
Having been a teacher, plus having 4 uni degrees plus being a fully trained librarian, I am always super conscious of referencing sources.
The image itself carried the source in this instance.
