People who lived in castles during the medieval times used them for attacking other castles and forcing them to surrender.
They didn't have glass (hence the shutters) and they were afraid of people getting in and attacking them (hence the size).
One way is to use a catapult to knock over the walls. This is useful as it distracts the defenders from protecting the gates and entrances, and may lead to desertion, which would allow victory to the attackers.
The castles were used to defend an area.
William the Conqueror made them to protect himself from attacking English rebels trying to knock him off the throne
there were no castles involved during the battle
I think that they were designed so that if the first wall fell to an attacking army they could retreat and make another stand on the second wall

Castles are stationary structures, not very good at attacking. Castles are mainly for defence. One option would be to open a gate and let cavalry out to attack the opposing army and then hurry back before the enemy made it up to the gates.
