Я нашла вам домашнее правило по Темной Стороне, ситы вы мои РПГшные ))

My ruling of dark side deterioration is this; Your Dark Side Score can exceed your wisdom, and for every five it does so, you take -1 to any random ability (rolled on a d6). This would explain how certain characters (most notably Palpatine) managed to keep the corruption under control (and even Palpatine failed miserably at that...). Vader is almost impossible to corrupt, since he's 'more machine now, than man'.
