In a practical sense, it's better to just kill him and take his heart. But Daedra hearts aren't that rare if you know where to look. There are many fixed locations e.g Babette Inventory post DB questline, Enthir Inventory, Mehrune's Dagon Shrine, Hall of the Vigilants etc.

The treasure he offers is not worth the inconvenience of having to scour the Icebergs of Winterhold just to find it.

In a moral aspect, entire depends on your roleplay style. Good guy, kill him. Bad guy, help him. Etcetera.
