Also, a debilitated planet can help create neechabhanga raja yoga, which can be a great asset to the chart. So for DB Jupiter, watch out for Saturn, Mars and Moon to see if they are over performing!
I know a person a close relative who has debilitated Jupiter in her sixth house..Leo ascendant.
She is like never satisfied and has abandoned her old parents citing "they did not buy her things when she was a child".
Also made her own brother to be sent out of the house as she was insecure about the father's assets
After all this she keeps attending family gatherings as of nothing happened
Her sun is debilitated as well with ketu and mercury.
To make matters worse her Venus is also debilitated conjunct with mars in second house.
How on earth I feel she is not feeling guilty or embarrassed?
I know someone fairly well with DB Jupiter in first house with Rahu.
What I can add is that there is not a sense of righteousness at all, zero. There is justice, but that is from Mars being strong. No spiritual inclinations come from Jupiter, there is some feeling toward spirituality but that comes from Sun and Moon in the 12th and Sag and they respect it but can't really engage.
Just like previous commentators, @kam have said they are overly involved with Venusian lifestyle and collect material things on a fairly vast scale. "Worldly" concerns take up the time along with entertainment and art being life's highlights, especially since Venus is in the 11th.
When stressed they don't try to do "what's right" according to any principles but try to do what benefits the most or what saves them from harm (survival = Saturn).
They are able to make a good amount of money due to 11th house placements and a pretty good 2nd lord, but make quite questionable decisions of finances and spend a ton of money.
