Very well, then. Let Mendev be as corrupt or dystopian as may be; Abramo owes it no loyalty. But the enemy of his enemy is, at least, an ally of convenience; and in less than a day, the demons and their cultists have made it very clear that they are hostis humani generis, enemies of all mankind. The navies of Venice fought pirates, too, in their day. That is the purpose of warships, rightly understood: To make the seas safe for peaceful merchantmen. And though Abramo is in his heart a merchant of Venice, though he has sat board meetings and declared dividends and guided cargoes east of Suez... the truth is that his life's work, his most notable achievement, is to be a man of war.
And that, if Abadar wanted men whose comparative advantage is in truck and barter, there's no shortage of them in Kenabres. And hiring good guards is also an important skill for a merchant.
He straightens his back and comes down off the barrel. He is the workman now, and not the capitalist; but the best workers are ambitious and have initiative... and there's evidently no shortage of tasks, in his new job. Ending the war with the demons will be a fine journeyman piece.
