I hold the old view that justice is a source of strength rather than something bought independent of it.
There is honor even among thieves. For example, a just group of thieves splits the bounty and return to steal together again as a team with improved skill, trust and cohesion. Sure they are scoundrels to their community, but they are just with each other. If they weren't, they'd in-fight and become weaker. This is true of militias and painfully obvious when two groups of forces lose faith, trust and a sense of justice with each other.
So I think justice is a virtue, and I think it's safe to say virtue is a source of strength.
Average-wise, would you think majority of humanity fits within this view?
I was born in a 3rd world country, grew up there and now live in a 1st world country. I think in many 3rd world countries, a lot of small time criminals and prostitutes did that because they have no other choice. They have no good jobs, or any jobs. They have no home, no family, no means to pay for their sick children or families. Not saying that people who have those still won't steal.
Wikipedia on Shaw's admiration of Hitler, Mussolini, and Stalin:
"""
Shaw's admiration for Mussolini and Stalin demonstrated his growing belief that dictatorship was the only viable political arrangement. When the Nazi Party came to power in Germany in January 1933, Shaw described Hitler as "a very remarkable man, a very able man",[1] and professed himself proud to be the only writer in England who was "scrupulously polite and just to Hitler".[2] His principal admiration was for Stalin, whose regime he championed uncritically throughout the decade.[3] Shaw saw the 1939 Molotov–Ribbentrop Pact as a triumph for Stalin who, he said, now had Hitler under his thumb.[4]

Undershaft. Yes.
Cusins. Anything out of the common?
Undershaft. Only that there are two things necessary to Salvation.
Cusins [disappointed, but polite] Ah, the Church Catechism. Baptism and —
Undershaft. No. Money and gunpowder.
Cusins [surprised, but interested] That is the general opinion of our governing classes. The novelty is in hearing any man confess it.
Undershaft. Just so.
Cusins. Excuse me: is there any place in your religion for honor, justice, truth, love, mercy and so forth?
Undershaft. Yes: they are the graces and luxuries of a rich, strong, and safe life.
Cusins. Suppose one is forced to choose between them and money or gunpowder?
Undershaft. Choose money and gunpowder; for without enough of both you cannot afford the others.
Cusins. That is your religion?
Undershaft. Yes.
