What is tone of regret

Like, put your tone a bit sad, but guilty at the same time. Some words of regret is "I wish I hadn't done that (sigh)" "(sigh) I feel bad I did that" "I really wish I could take this all back (sigh)"

You see, like, the regret tone is mixed with sadness. Take the "i feel bad I did that". The sigh was sadness, the "I feel bad" was guilty, and the "I did that" was just overall both.

the word that best matches the meaning of the expression "went to the big ocean" is died.

the goldfish died, which is why the father looks at the children mournfully. the "big ocean" is the father's way of saying fish heaven. he could have just said that the goldfish died, but this way, the children imagine the fish in a bigger, better place instead of just picturing a dead fish.
