I have never hated Duncan, however(underline) I must admit that he could be a bit of an jackass at times.The most explicit examples would have to involve; keeping important military information from Loghain and the Cousland Origin. In the first one he should have taken into consideration that he might die in the coming battle and thus someone in power should know about the Archdemon/Warden connection. In the second unless you decide o become a Warden he will not allow you to escape from the ,castle?, then if you decide to attempt to save what is left of your family bam! conscripted.
Duncan did have his rather redeeming moments in the other Origins. In the Dalish elf origin he allows you to stay for Tamlen's funeral and say goodbye to your clan. Dwarven Noble, after fighting your way through miles of the deep roads he recognizes who you are and formally invites you into the order. Dwarven commoner, saves you from being executed. City elf, gives you weapons to save your lovely bride and saves you from the guards. Magi is rather neutral.
