How does Suskind explore obsession to convey the moral consequences of Grenouilles' actions?

The moral consequences of Grenouilles' actions are far-reaching - beyond the consequences to himself, they stretch to society, invoking strong emotions in others through the creation of his scents. Please assist in helping me to explore how Suskind uses Grenouille's obsession with creating perfumes that invoke these emotions in others, and the moral consequences of his actions, including any thoughts you have on how, despite his obsession with wanting to be hated (in order to have legitimate identity), he manages to create a scent that does the opposite - at a time when everyone should hate him, they find themselves extending love towards him.

I'm assisting my son with his essay question (above) and would appreciate your thoughts.
