Does the word theft need a legal definition to exist?

Outside of any legislative bodies jurisprudence, so the open sea, or Antarctica, on the moon or in open space perpendicular to our ecliptic, is theft wrong based off a legality? Or is theft considered wrong based off a morality?

Legal≠right, ≠fair, ≠justice, ≠moral

What is legal is entirely it's own thing. And even at that, if someone breaks the law, but then no one applies the consequences of breaking that law against them, is that even a law then?

When the law is arbitrarily applied, like how the rich tend to not be charged with first offenses and just get warnings, then that teaches the privileged to not worry about the law, to move fast and break things, to ask forgiveness rather than permission. But when the winning class doesn't respect the law and every class under them is constantly looking up for cues on how to rise, weeeeeell...

The law applied unequally results in no one respecting the law. And that's the rational response. Corruption kills communities. Corrupted leaders are effectively undermining our society, regardless of their title, be that Senator, General, Judge, et al, they're sappers, undertakers, saboteurs

We need harsher punishments, across the whole of life, for people being deceitful, spreading mis/disinformation, telling half truths and lying to any degree.

The entire foundation of human culture is built off trust and an adherence to an objective truth outside our body. What do you think faith is? What do you think spirituality is? Religion is merely a groups adherence to what they consider to be the universal truth. At the core of how we perceive, ourselves, society, existence as a whole, we have a universal, biological, demand for the truth.

And I think our law should reflect that to a higher degree. Like if repeated theft can lead to life in prison, one case of embezzlement that results in the theft of 1000s of retirement accounts should be met with an execution.
