In some fanfiction, it might be a misguided attempt at protecting Ginny. Dean could believe that she's in some sort of danger that she doesn't see, and so he takes extreme measures by kidnapping her to keep her safe. However, this is a very dark and unorthodox way of 'protecting' someone. Another possible motive could be that Dean has been influenced by some dark magic or an outside force that has warped his mind and made him do this against his normal nature.
Well, it could be out of jealousy. Maybe Dean feels like he's losing Ginny to someone else and in a moment of madness, decides to kidnap her. But this is all just speculation within the wild world of fanfiction.
It could also be for power. Perhaps Stiles has some knowledge or ability that Theo wants to use for his own gain. In the show, Stiles was quite smart and resourceful, so Theo might kidnap him to get access to that intelligence or those skills. In some fanfictions, Theo might be trying to use Stiles as a bargaining chip to get something from the other characters like Scott or Derek.
