The Morean war’s conduct first convinced Mehmed Ali to defy the Sultan.

Evidence

Although it might be true that Mehmed Ali felt this fundamental incompatibility of interests right from the beginning of his career, it does seem that what finally prompted the Pasha to rebel against his Sultan’s imperial wishes was the manner in which the Morean war was conducted for it is during that campaign that the seeds of rebellion were sown that ultimately led to this first clear act of defiance by the vali of Egypt against his Sultan. Specifically, it was concerning the manner of conducting the war against the Greek rebels in the Morea that the Pasha discovered that it was impossible to collaborate with the Ottomans in any future wars. — Khaled Fahmy, All the Pasha_s Men_ Mehmed Ali, his…, 226
