iCloud keeps signing in after I sign out

iCloud always... ALWAYS crash all my apps (Pages, Keynote, SimpleText,
etc) that use iCloud so if I turn off iCloud, the apps run fine. Apps just
cannot open documents at all.
Here's what's getting my goat: I signed off iCloud in System Preference on
Mac OSX Mountain Lion but every time I open the System Preference, it
shows that it's already signed in! That's how I know apps aren't working
if I use them again in few minutes. Something is wrong. I have to keep
signing out every time I open System Preferences.
I want to totally disable iCloud and removed from MacOSX if possible. I
don't want photosteam, I don't want data shared in the cloud.
