It is their personalities... my two boys, seven years apart, were (and still are) just total opposites.
But as to how you handle it, try distraction. If he starts to tear up a book, as you take it away from him, quickly and firmly, saying "Oh, no, no, we don't tear up books," you swing him around and point at whatever you see, and immediately launch cheerfully into another subject, for example, "Oh, look at the kitty!! Look at the kitty in the yard!! What's that kitty doing?!!" And you continue until he has forgotten the book and is involved in something less destructive.
Or you take the book, and ignoring his shrieks, swoop him up and carry him out of the room, cheerfully chatting about what to do next, for example, "Oh, no, no, we don't tear up books! Let's go find some construction paper we can tear up and make pictures with, don't you think that might be a good thing to do?!!" Just keep talking cheerfully, and setting up a situation where he can use that "tearing up" energy, but use it on something appropriate.
And you CANNOT allow him to injure his sister or "smash a toy on your head," or anything like that. You just have to stop that stuff right away, fit or no fit. If you stop him and he starts "having a fit," let him holler. Don't argue or explain, other than to say "No, that hurts, and you cannot hurt other people," or "No, that might hurt your sister, and you cannot hurt other people," so that he understands that there will be no tolerance for this kind of behavior. Then look around for something to serve as a distraction.
