*Looks at the formation of the Republic.*
*to self*: "No, you're better than that."
Okay, my two votes are for Victor's decision to try to lie to *Not-Marik* about his kid dying while under his care, and then replace him with a double for one.
And for two: Victor trying to use Katrina's pet assassin against her.
For the stupid thing with the Marik (or not-Marik) kid; this was just a dumb plot device. Chalk it up to Victor's inexperience, his state of mind, with IIRC; Hanse recently dying, if you want, but it was poor judgment front to back.
Thomas was a famously honourable man and there were bound to be negative consequences for lying to him. It's even plausible that his military aid would have continued as a memorial, after the kid died.
But to double-down on that with a rehash of a failed plot from before the 4th SW...Wow. Just wow.

As for the Assassin-thing...this was just stupid soap-opera nonsense. It showed a total lack of common sense and Katrina played it out like the straight line it was, Victor lost tons of credibility and gained nothing he couldn't have had from his own means already.

As an aside...it seems like we're dunking on Victor here a lot. And we are. And he deserves it.
But he's also the leader we have seen the most of through many of the classic novels, so additional exposure gets him that. But he's also a victim of writing and a product of the mind that formed him; Stackpole.
It's not that Victor comes to us as a well-meaning screw-up, but rather as the bag man for a vast collection of unfortunate tropes that pass for motivation, character and plot development.
