to regret
To feel regret and remorse about a past action or decision and wish one had acted differently.
Er bereute es zutiefst, seine Freunde angelogen zu haben.
He deeply regretted having lied to his friends.
'Bereuen' (to regret) is derived directly from the noun 'die Reue' (remorse/regret). When you regret something, you feel remorse about it.
Er zeigte keine Reue für seine Tat.
He showed no remorse for his act.
The verb 'bereuen' (to regret) can be used in three ways: with an accusative object, with a 'dass' clause, or with an infinitive construction with 'zu'.
Ich bereue meine Worte.
I regret my words.
Common things people regret are 'eine Entscheidung' (a decision), 'eine Tat' (an act/deed), or 'Worte' (words). The feeling is often intensified with adverbs such as 'zutiefst' (deeply), 'bitter' (bitterly), or 'sehr' (very much).
Später hat er seine Entscheidung bitter bereut.
Later, he bitterly regretted his decision.
to regret / pity
Both words can express regret about one’s own earlier action or decision. „Bereuen“ usually emphasizes personal remorse and the wish to have acted differently, while „bedauern“ can also sound more neutral or formal. „Bedauern“ often fits a matter-of-fact apology, while „bereuen“ is used for strong personal remorse.

In meiner E-Mail an den Veranstalter bedauere ich, die Einladung abgelehnt zu haben.
