parent-child - CQRS: How to correct missing events from the past

Question

In our application that uses CQRS and eventsourcing we have comments and replies. In the past if we deleted the comment we didn't delete the replies. Now we want to make sure the replies are also deleted.

How best to solve this:

• Create a list of replies that should have been deleted from the eventsource table and delete them after the comment was deleted.
• Create a new deletedCommentEvent that has a new property "HasDeletedReplies" and handle both events differently so this takes into account if the replies have been deleted yes/no.
