Holy shit almost missed the most important intel!

Getting tricked/programmed into killing our saviors/family/loved ones from space/outside of earth etc.

Solo after he escaped earth he couldnt make it out with his loved one so he was planning to come back stronger and rescue her.

When he came back years later he found her to have risen in the ranks of the lunar scum/being part and loyal to them and when he was fighting the lunar boss at the end to save her as he was going to kill her she stopped him and went on to kill him!

HOLY MOLY MAN! AND MOST LIKELY THAT'S WHY THE LUNAR BOSS HAVE US IN HIVE MIND SYMBIOSIS WITH HIM SO HE TAKES OUR SAVIORS BY SURPRISE, EVEN THOUGH I KNOW WHAT HE'S PLANNING TO DO, IN MY SLEEP PARALYSIS EXPERIENCES I BECAME AWARE HE/SHE CAN TAKE CONTROL OF MY BODY ANYTIME(AGENT SMITH/AZAZEL STYLE) AND HOW HARD TO IMPOSSIBLE TO BREAK FREE/TAKE BACK CONTROL IS!

The tattoo/mark of the beast solo's loved one had on her hand is symbolism of the symbiosis and mind control the lunar boss had on her.

-Once you're a part(assimilated black goo style/joined the hive mind)
of Crimson Dawn,
you can't leave.
