I don't like the thought of my favorite Zabarak dying isn't the game depressing enough in places? I don't mind conflict and a certain amount of angst, however all Doom and Gloom is hardly my idea of escapism.
As opposed to just dying off-screen, which is currently the case?
This mod's usefulness is subject to opinion and not everyone would be using Kainzorus' mod.
Because Stoffe didn't program it that way.
If you add an entry, you only need to update the StringEntriesOffset in the TLK header and splice your new entry into the end of the StringData cluster before adding the actual text of the entry to the very end of the StringEntries cluster.
If you edit an existing entry, you need to update the StringEntriesOffset in the TLK header, the Offset in the StringEntries cluster for the edited entry and every entry thereafter, and then edit the text of the entry in the StringEntries cluster, which (depending on how you did it) may or may not involve adding or removing bytes if the entry contains more or less text respectively...
Just going by number of processes, adding is definitely easier than editing.
Well, if that was the easier way to do it at the time, then so be it, but that's also a pretty fundamental flaw and seems like a pretty common use case for modding.
