Whether the information was accurate or not, it wasn't a loss for the Continental Hotel.
Also, the person who leaked it was the survivor who had nothing to do with the hotel.
It didn't matter who wanted to go to war with V, but the Continental Hotel wouldn't be their pawn.
As for the deaths of the 126 hitmen, what did that have to do with the hotel?
The hotel was only a platform which provided intermediary and logistic services. It didn't have its own assassins, nor was it a training agency for killers. Winston didn't care about the deaths of a few killers.
There were thousands of such killers in the database of the Continental Hotel; it was normal for one to two hundred to die every year.
If more than a hundred of them died, then two hundred of the elites who were on standby would be sent forth. This had always been the case.
Assassins were always expendable.
