Derek felt that he needed a pack to stand up to the Alphas. His choice of Betas, with the exception of Isaac, was not very good however. Then again, the Bite had failed on Jackson in a spectacularly bad fashion. So he might have been scared of Biting somebody he cared about (e.g. Stiles), or who otherwise had a good life (e.g. Danny). Instead he chose kids with bad lives, so that he could rationalize that he was helping them somehow. Scott kept refusing to join up with him, Lydia was immune and Biting Allison would have provoked open war with the Argent's.

Pity, because a pack consisting of Scott, Stiles, Allison, Lydia and Danny would have been made of win!

Colton's departure was very last minute, so the writers were clearly scrambling to catch up. The same was true of Gage, which is why so many of Cora's early scenes were very obviously written for Erica.
