It’s not always a choice. If value has been transferred onwards (ultimately in the form of e.g. cash withdrawn or something equally hard to trace, like physical goods handed over to a buyer), simply “undoing all transactions in a database” isn’t without victims either.
Whether undoing transactions or not is an option strongly depends on how fast value is allowed to move. Sometimes being slow is a feature as much as it is a bug.
