Alexander did not feel like explaining himself why he killed the nobles.
The real reason why he did so was so that he could take over their lands without any contending, or at least strong contending claims against him.
While Ptolomy might have preferred these nobles because they would be more loyal to him than
Alexander, which was the cause of Seelima's displeasure.
And as for killing Maizdy, not to mention his rotten nature, Alexander had already snatched Muazz's most precious son from him, the city of Zanzan.
This made the two men unable to live under the same sky, so why be lenient now?
Hence, Alexander simply decided to move on, and got down to remind the table of the real problem here,
"The nobles said that a 40,000-50,000 army which has 10,000 Jahal mercenaries will be attacking Zanzan. And they seemed pretty scared of this unit. So do My Ladies know anything about them?"
Alexander posed this question particularly to Mikaya.
