Did feudalism create a stable form of government

I would belive the answer is no

After Rome fell there was no structure in society.  No one took care of the roads, the aqueducts or other businesses.  Feudalism supplied a form of structure and protection people did not have...before feudalism is was nothing but chaos.

Feudalism was a good form of government, but it could use some work. First, the idea of a social structure is unfair because if you were born a peasant, you would never become a knight or a noble, you would just stay a peasant. Secondly, nobody treated the peasants and serfs nicely. Everyone is a human being, so everyone should be treated the same! Lastly, everyone should have the same amount of work, because the peasants did nothing but  work.

No he did not do a good thing at all to be a good government you must be strong at heart

Yes. Feudalism let knights get land grants from lords or nobles as long as they served in time of war also known as military service. These knights made peasants labor them. I'm learning about this at the moment too, I hope this helps!!
