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?
