Thinking about creating an evil character in Mass Effect

As you may know by now, I have just hit a snag on my progress in Mass Effect 2 since my brother loaned it to a friend (just finished disk one around the time that happened) and so it might be a while before i can finish that game (though if I get the extra money, I might get a new one).  Anyways, I am thinking about playing through the games a second time through and this time make a 100% renegade (or evil character).  On the first time through, I ended up creating a Han Solo type (someone that is in between paragon and renegade), but now I am thinking about making a renegade character.

What do you all think of that?

Making a renegade character on Mass Effect

I actually recently bought Mass Effect 2 for my brother for his birthday.  However, I have not beaten Mass Effect 1 yet, but I have decided to make my guy go renegade.  As a nickname, I named him "OJ Simpson Shepard" as a cool villian name for him.  However, he will not be entirely evil and will have some good in him.
Will post updates on the game over time.  Currently, I just beat the Matriarch boss and getting ready to go to Feros (though I might do some side missions as well)
