Indeed.
Except that you have to be extremely well prepared for at least one real fight against an ALPHA (the white werewolves), if possible so we need to have little or no damage. (most of the time it's impossible to do, then usually we just have to seduce them because of the fact that they take far too little damage) - so, at least, to reduce his power over others first, and then take control by seducing him completely and then taking him as much as we becomes his Alpha (we take his place), this will allow us to take power against all the others werewolves.
To sum up, you have to have at least one real fight in which you have to make him as weak and as submissive as possible. (in other words, reduce him to simple werewolf) - and it will be reflected on all his descendants, and therefore Bernard and Logan. (if they're still werewolves then)
This part of the story is very hard and complicated, and that's why it's recommended not to have anything special to do during this time.
