In Islam, angels are creations that are created for the sole purpose of praying to one god and they are not capable of disobeying god. They're not humans they can't have human emotions or can we explain their emotions in human terms.
Believe it or not, many people may interpret angels as not loving nice creatures, many people see them as beings to only worship god. At least in the Christianity section, I have not read or studied the Quran, so I have no idea about the Islamic faith.
