I just got back from a long trip in Texas with an entire medical emergency ordeal finished with

. For those who don't know, my mom went unconscious for a while (which actually turned out to be caused not by her cancer, but by the lobonox or something they gave her.. ugh), but she recovered. Although it should be a happy thing, it's not really. We're all stressed and basically returning to old habits, where we go into separate rooms and ignore each others existence. A tad gloomy and depressing, but I'm going to college next year anyways. *shrugs*
What does that have to do with points of view?

Well! I've decided to throw myself back into my creative side, and begin drawings and what-not again. It's a great stress reliever, and helps to take my mind off things. There's the only problem that my happy-happy draw pictures side hasn't woken up yet. It's still kind of shell shocked. Whenever I pick up a pencil, pen, whatever... I just can't seem to do anything.
All the above stated (in a rather lengthy way, sorry 'bout that

) I'm starting up writing again, and am working on a book which I started writing a little over a year ago. I made the mistake a while ago of breaking the book into two halves, and now I need to make it into one again. So, I'm starting a rewrite to keep some consistency and hopefully along the way bring back my happy-happy drawing side. Except, I need some opinions, and I thought of no friendlier or better place to ask then here.
My issue is that I wrote the book in a strange perspective, alternating between two characters at random intervals. I've decided I need to focus on one and stick with that character, because two even get me confused! And with the dinky plot and history encompassed in the book... I don't need it any more confusing!
So, I have two choices to follow, and both are completely open to me. I just want to know what you guys would think would make a better story.
The basic plot is an assassin, controlled by “evil forces”

, is told to kill a certain person without any knowledge of who that person is or why. Said assassin finds the target, fails at killing the person like 5 times, and decides to follow them, becoming friends along the way, of course! So these two travel around, the assassin trying to figure out why they need to kill this person, and the target trying to figure out why there's an assassin after them. I can either write from the point of view of the assassin, or, for lack of a better term, the target.
I'm being kind of, erm, subversive? about who they are, because I partially want just raw opinions, but I'm also still kind of shy about it. If there's anything else I need to detail, I'll happily throw out some more information on the characters/plot/ideas/theories/etc...
Anyways! Sorry for the large post. But, in short, who's point of view should I write from? The assassin or the target?
If this would be better in the Fan art and creative writing rather than off-topic... feel free to move it. I couldn't quite figure out where to place it...

Technically I'm talking about a book, but it's nowhere near finished or anything. Then again, it IS creative writing, but I'm not posting the writing up yet, it's a question about the writing... Gah! I could go on all day about its x,y, and z, but then again its q too, but it should be s to go in, then again h, e, and w all seem... *bashes head against wall*
