I've always been confused about this placement, and i want to know if you can help me with it.
This can be good for careers in security and defense.
My cancer mars is in the 12th with a link to the aries MC. Most of my career has been spent in defense industry that has a lot of secrecy elements to it.
Hi Yann. Its a very powerful Mars, as Wilson says. Its on the MC, square the Asc and semisquare the Asc/MC midpoint. But there may be some effort needed to express and fulfill it because you have Libra rising (ruled by Venus in Libra in the first house) and also Moon in Aquarius. So you are predisposed to behave (Moon and Ascendant) in an impartial and ethical manner. But Mars in Cancer is motivated by instinct and personal values, so there is tension here and a need to find ways to channel that Mars energy in a way that doesn't upset the airy Moon and Ascendant.
Sun in Leo is more dramatic, especially when square Pluto, so the Sun and Mars together may feel like a handful sometimes. Or it could be that you're OK with your passionate side, but feel like you have to fight your way through the ethics and notions of others when you're trying to just get on with something.
All in all its a nice balance between passion and social/ethical awareness, as long as you can embrace both sides of your nature. Meanwhile Mercury in Virgo in the 12th (and also Saturn in Pisces in the 6th) will be trying to remind you of what you need to do to stay properly synchronised with the world around you, in a way which enables you to meet your emotional and physical needs.
Actually, I was just looking at Mozart's chart. He had a retrograde, out-of-bounds mars at first degree cancer. His chart is overweight with harmonious aspects. His work was primarily motivated by inspiration, but he was also under a lot of stress with his financial situation towards the later years (don't forget transits).Strong placement but perhaps not enough motivational energy or direction behind it, all those easy aspects, to forge goals and act to achieve them.

In the mean time you could consider what fears cause you to sometimes express what you call a condescending approach. Perhaps the fear of insignificance or annihilation. Making peace with any such fears will probably help with your problem. And then your Libra/Venus first house will feel more comfortable because you will be able to more easily fulfill your need to approach the world with social awareness.
