Looking at it from another angle, the conclusion was indeed different.
Deathstroke had always stood on humanity's side. He viewed demons as "Alternate Dimension creatures skilled in deception," and remained vigilant at all times to avoid being tricked.
So when demons spoke, he was inclined to believe that 9.8 out of every ten sentences were lies, while the remaining 0.2 were riddles that required careful analysis.
If a demon told him it had eaten one bowl of noodles, he would assume it had actually eaten several—and want to cut open its belly and count for himself before he could rest easy.
That was normal human thinking. What decent person would believe a demon's words?
But from Satana's perspective, demons had no need to deceive Deathstroke and Doom over such a trivial matter.
There was almost no benefit in it, while it would needlessly provoke two powerful enemies.
The Sorcerer Supreme was the one who called the shots in the Magic World of the Main Dimension. Leaving aside the desperate trump card of severing Hell's connection to the human world altogether and creating some Heaven-like dimension to replace it—
If he merely organized mages to intercept Hell's lending business in the human world, many Demon Lords would already be in for hard times.
For the soul of one Enchantress, angering the Sorcerer Supreme was absolutely not worth it. What demons wanted was not chaotic war, but benefits and profits gained amid chaos.
With no benefits and nothing but downsides, not even a fool would make that deal.
There might be fools among demons, ones daring enough to deceive even the Sorcerer Supreme, but such demons could never become Hell Lords. Those who could not do the math did not survive long in Hell.
