[General] good riddance/at best/at worst

[vil]

Dear teachers,

Would you be kind enough to tell me whether I am right with my interpretation of the expression in bold in the following sentences?

The boys thought it was good riddance when the troublemaker was sent home.

When Mr. Roberts' old car was stolen he thought it was good riddance.

Betty thought it was good riddance when her little brother broke his toy drum.

Compeyson took it easy as a good riddance for both sides.

good riddance = a loss that you are glad about

"I'm going and won't come back," said John. "Good riddance to bad rubbish!" said Mary.

good riddance to bad rubbish = a welcome loss or departure (to show that you are glad that something or somebody has been taken or sent away)

There is often disagreement between spouses; wives complain at best about lack of help and support from their husbands, at worst that their husbands make increased demands and take out their frustrations about the relative on their wives.

at best = under the most favorable circumstances

at (the) worst = under the most negative circumstances, estimation, or interpretation

Thank you for your efforts.

Regards,

V.

This one sounds a bit forced to me- I can see the idea but it would be more a case of good riddance if he had lost it.
