Why did Hitler not realize that invading Poland would be a fatal

He was appeased to the brim.
Austria? Check. Czechoslovakia? Check. Poland? Why would this be any different? Also he acted like a child and demanded his demands be met without exception. Hand in hand, his megalomania probably lead him to believe it would be successful without retaliation.
>would things have turned out differently?
Likely not. Slim chance he would have waited and even then, if he did wait, it would have happened eventually. Even if he was appeased then, he would have expanded eastward more until war with te soviets was inevitable. Maybe if there was a war solely between those two states the Nazis may have won (unlikely) there is a limit and he probably would have attacked westward eventually.

Hitler was confident that Britain and France would not honor an alliance with Poland to maintain appeasement, and if they did, Germany could win another European War with the USSR not involved.

and Hitler's war was going even better than planned until the battle of Britain, with France knocked out in just 6 weeks and Britain on the ropes, but Hitler's failure to bring the British to the negotiating table in time came back to haunt him in the long run.

If Hitler didn't invade Poland, Germany would've been faced with economic collapse from their extreme overspending on rearmament and other projects. Hitler's plan from the start was to take immense loans that Germany could never pay back on its own weight, and conquer territory and use the spoils of war to keep the economy alive. If no such conquering took place, Germany would've had to default on its loans in the early 1940's, kicking them back to a severe depression just like the 1920's.

Hitler planned out the conquest of the entirety of Europe and the conversion of that land to be Lebensraum for the German people. There was no way he would never invade Poland, the war was happening as long as Hitler was in power.
