I recall Zalbag sounding unhappy about having to give that order. Something along the lines of telling Algus to, "Go on! Do it!" But maybe it's different in the PSP "War of the Yon Large Feline that verily doth Roar forsooth"

This along with the way he reacts to Dycedarg's killing of Prince Larg among other things leads me to the conclusion that Zalbag was a beta who typically followed his brother's orders, and finding out about the poisoning plot was the last straw that lead him to finally grow a fuckin' spine.
