Theft and murder?
I know that they're wrong, but they're not in the 7 deadly sins. Wrath, greed, lust, gluttony, pride, envy, and sloth. Now I guess you could murder someone out of envy and steal because you're too lazy to get in on your own. But still, it's not like they're hard to get wrong.
Now if you're talking about the actual mortal sins, new sins that the catholic church added, you're still wrong. -shrug- :\
In any case, my nit picking aside, good game.
