Cancer isn't a passive sign. It is a cardinal sign which means action and ambition. But it is also very emotional and sensitive, that is true, and when you have Mars in this sign, it means that your actions are governed by your emotions. You don't think much, you just do, especially with Aries on Ascendant. And most of your doing is focused on building your home and your family. Youre private place, or circle wher you can relax and feel save. Or even, since your Moon is in Aquarius, not a place or home for yourself, but for all those who do not have a home or family. So you can be quite active but quite unstable person that always acts according to his heart.
