if i may point out, peter said almost verbatum, "a werewolf can't steal a true alphas power, but a werejaguar with the power of (insert that churchs name here) behind her, maybe she can"

so if peter was still teamed with/using kate at this point, she may have had a way to transfer his alpha power to peter that wasn't mentioned in the show. this would have bee mutually beneficial for them, as kate would get to see scott die and avenge allison and peter would get alpha status back.

so it may not have been purely a ego trip for peter, in trying to kill scott.
