Not that it makes it any better, but isn't that what all empires are built on? A more ethical empire wouldn't be an empire at all. It'd be something more akin to the USA, the EU, or on a smaller scale the UK itself.
And yes they're totally second class. That's why they have their own parliaments whereas England doesn't.
Yes, the fact they have their own parliaments, while "England does not", does indeed demonstrate that they are second class. Because the reason England "doesn't have a parliament" is that when Scotland "joined", the English parliament was simply renamed into "The Parliament of Great Britain", without changing anything else. They even kept the same MPs - didn't even hold an election! It was all for show, a minimal mask of fairness for dissolving the Scottish parliament. It resulted in riots and martial law.
This, by the way, was the closest England ever came to "consensually" adding a member. Wales at this point in time was a straight-up English territory. It didn't even get a parliament until 1999, at the same time Scotland was allowed to reform theirs. And would you like to talk about Northern Ireland?

Are you suggesting that the US behaves ethically? Snowden, Assange, Iraq, Afghanistan, Vietnam, BLM, Guantanamo, ...
Or the way the native population was treated. (theft and oppression)
