I would hope there is nobody who admires Alex as a character. He's a yob, delights in assaulting people and I can't remember if he actually kills anyone, but if not, it isn't for want of trying. the issue is whether it is acceptable for the state to use brain-frying / Operation / whatever methods to turn him into a conforming citizen. Perhaps that part is a satire on the street-to-prison pipeline where many people (largely young men, very often ethnic-minority) inevitably end up in prison for reasons that are almost cultural by now.

The other salient feature of the book - as with 1984 but in a very different way, is the language. Nadsat (from the Russian word for 'teen') is a young people's slang peppered with Russian words, e.g. 'droog' for friend, 'malchick' for boy, 'devotchka' for girl and so on. No explanation as far as I can tell is furnished for the presence of so much Russo-slang in the mix, and it's a long way before London English became as it is at present (part American-influenced English, part Caribbean, with imports from still other places).

You raise the blade
you make the change
you rearrange me
'till I'm sane

which was still popular as a method in the 1960s, as it was in the 1910s and 20s when Zamyatin was writing We. Is it help or conformity? Your language may vary.
