About this pattern

Explanation

ばよかった expresses regret about a past action or decision—“it would have been better if…/I wish I had ….” It’s used when looking back and feeling that something should have been done differently. The form is the conditional 〜れば attached to the verb’s dictionary form (for most verbs), followed by よかった. It’s more natural than saying 〜べきだった and focuses on personal regret for past choices. Typical contexts include missed opportunities, mistakes, or things one now wishes had happened. Examples reflect what the speaker wishes were different in the past.
