Storing the errors alongside other transformed inputs is a really good idea. But manually patching up and/or deleting individual records is a really bad idea! How is that going to help your data integrity? Surely you want to fix your importer and re-run it. If there was a smart tool that was able to avoid duplicating work and only re-import the affected records, that'd be great, but that doesn't seem to be what's shown here.
