"I think Mavis contracted the Curse due to using Law."

Gee... I wonder where you got that idea... Oh yeah, probably because the manga outright stated that this is the case...

"the Curse targets those the cursed deems friends/loved ones."

No the curse targets literally everything. Friends, enemies, animals, plants... everything that's alive. The trigger is completely random, with the likelyhood rising the more the affliced values life. It matters not who or what is in the vicinity.

We've seen Zeref fire off the curse when he was surrounded by wolves that tried to eat him and later while he was carried by Zancrow. Do you think that Zeref was having a secret affair with one of the wolves and had a crush on Zancrow?
