Q: better off / worse off を使った例文を教えて下さい。
A: I feel it’s also worth contributing the difference between “worse” and “worst,” although only one was mentioned

Both terms can be considered relative, although the former is more to simply say “more bad than something else”
While the latter means it is the most terrible situation

🔅Therefore, in this case, the term “worse off” shows the resulting affect of an action putting the subject in a more difficult position than they would have been otherwise
🔅With the opposite meaning, “better off” has the same usage (subject is in a relatively better situation because of an action)

(Just as extra food for thought, or review if already known :) )


Q: "Is it getting more worse with people (rude, loud, unrespectful, agressive, violent) behavior ?"


"Is it get more....?"

wich one is better/correct ?
A: "Is it getting..." is better than "Is it get...".
"more worse" is incorrect: you can say just "worse" without "more", or you can say "worse and worse" to describe a downward trend.

Q: She is not better than him. She is just less worse than him. この表現は自然ですか?
A: Haha, that does make sense, but it is not grammatically correct. You would probably hear this between people in casual conversation. The wording you have used could also be used in a humorous way. To be grammatically correct, for such purposes as academia, it would be: "She is not better than him, she is just not as bad as him" - it is also only one sentence.
Despite all of this, I have said it sounds natural because it is definitely how I have heard people explain it before, and it is really useful in conveying that both are bad, but one is worse than the other.
