While we wait for you to get your chart in order, here is some useful information reposted from another forum:
Maybe the idea behind this is that these are all humane sign that are the target of the aggressivity of the native.
Generally speaking for psycopathy surely the 12th house and its ruler are to be watched.
The star Algol seems related to folly and violence, also other stars could give similar results, but with less regularity.
About aggressivity surely Mars has something to say; we should also see how are interacting lord 1 and lord 7th, but also the interaction with lord 3 (neighbours, casual acquaintances), or lord 9th (for tendencies against strangers) and lord 4th (for aggressivity in family).
Also the 8th house and its lord can give suggestions (sometimes even the 2nd as turned 8th).
In general any unbalancing element in the chart can bring a psycologic pathology.
It is very important watching the Moon, for example an aspect between Moon and Mars or Uranus often gives hypersensitivity.
Neptune can be mentally confusing if afflicting Mercury, the lord of the ascendant (or even the ascendant itself), the Moon and probably also with the Sun can give this result.
There are also some arabian parts like sinos that can help, or an affliction to the part of fortune or that of the spirit and their lords.
The instruments are various, we can choose ours, if there is really a problem usually it is repeated in many ways, so one doesn't have to use all the instruments he knows.
As for your chart I do not know anything of you and of the contextof your life, so the error margin is high, but I will try say something:
you have Mercury lord of the ascendant in its terms and in cazimi, this would be good; but the Sun is also the lord of the 12th house (isolation, in case self destruction), both squaring the Moon, not the best thing, the more so with Frawley's reception system because the square is from the Moon's detriment, so they are hostile to the Moon (and the Moon to the Sun, being in its fall). The lord of asc in cazimi could indeed suggest narcisism.
Mercury is also retrograde, this can bring greater introspection, reducing the outward activity.
In traditional astrology the "significator of manners" (the planets that descibes your behaviour) is the planet that has a link with both Moon and Mercury, in this case we would have Saturn received both by the Moon and Mercury and the Sun for its conjunction with Mercury and the square with the Moon, these are of a rather different nature, but is interesting their mutual reception. So you seem alterning from a "solar" enthusiastic nature to a more reserved and maybe gloomy one with occasional emotional crisis and outburst (Saturn in Aries sextile Uranus; Mars is in Virgo so I personally do not consider it opposed to Saturn since it isn't in Libra but, being in the 1st house, probably adds some aggressivity).
There is a mutual reception between Mercury and Mars that is also lord 8th, so you seem having a particular relationship with the violence and the idea of death, but this relationship is a bit conflictual since the Moon is in Mars' detriment and squaring Sun/Mercury.
Also the retrogradation of Mercury can complicate the matter since you are more focused inside yourself than to the external world.
About your relationship with others you seem in general not having a good opinion of them since we see Jupiter lord 7th in its fall and conjunct Neptune (do you see them confused/instable?) and Mercury and the Sun are also in the fall of Jupiter; Mars is in Jupiter's detriment and trining it while the Moon seems indifferent to it.
This surely doesn't mean that you will kill someone, but probably think of it more often than others, besides Mars is separating from Jupiter and about to change sign falling in detriment, this could mean a change in your self assertion style during the life, not necessarily for the better. Still, with a separating aspect that has already some distance, I think that probably you won't kill anyone.
