Play it you will enjoy it. As I am a Light Juggernaut. There is a whole STORY LINE within the game as to how and why it could and does happen. Even how.
You guys neglect to look at the WHOLE picture of the political / social views of someone from thee Sith Empire and some growing up in say the Republic.
So many ideological differences you guys are not taking into account you can choke on.
Tidbit on Crystals maybe this helpe
"Before placing the crystal in the lightsaber, the Jedi or Sith must imbue them with the Force. To do this, the Force-user must meditate on the crystals for many days. Luke Skywalker meditated on his crystal in Ben Kenobi's home for many days with only R2-D2 to keep him company.
While the Jedi used natural crystals, the Sith often used red-hued synthetic crystals. Sith-made synthetic crystals create a slightly more powerful blade when energized by the dark side of the Force, occasionally demonstrating the ability to "break" Jedi lightsaber blades, disrupting the energy circuit and shorting out the weapon, as almost happened to Obi-Wan Kenobi while fighting Darth Vader on the first Death Star. However, this rarely happened, and as synthetic crystals demonstrated a slightly lower amount of maneuverability, this advantage was very slim. Darth Sidious made Darth Maul use a special furnace to make his own crystals. Maul worked constantly for several days to make the four crystals needed for his double-bladed lightsaber. Their creation required intense concentration, as Darth Maul had to use the Force to make them the proper shape and to ensure that the crystals were free from impurities. He was particularly proud of this achievement and believed it to be an example of the Sith's superiority over the Jedi.
However, it should be noted that Sidious did not make his subsequent apprentices—Tyranus and Vader—create their crystals in such a manner, instead supplying them himself.
Luke Skywalker's synth-crystal generated blade.
Luke Skywalker used a special furnace he found in Obi-Wan Kenobi's home to prepare his crystal. In both Skywalker and Maul's cases, the creator channeled their Force energies into the crystals as it was formed, making it unique in every way, including in color.
Around 4,000 BBY, lightsaber crystals were used to indicate a Jedi's chosen class. Blue indicated a Jedi Guardian, a Jedi who used the Force on a more physical level. Green indicated a Jedi Consular, a Jedi who preferred to reflect on the mysteries of the Force and fight the dark side at its heart. Yellow indicated a Jedi Sentinel, a Jedi who honed their skills in a balance of combat and scholarly pursuits.
This distinction fell out of practice in later years when most Jedi used blue or green crystals based on choice, and the supply of them on various source worlds. Purple, yellow, and orange crystals were still used by some Jedi until the the fall of the Jedi Order, but they were exceedingly rare, and often passed down through generations.[source?] The Galactic Empire banned trade and possession of all lightsaber crystals.
During the Great Sith War epoch, many lightsabers were created using Kunda stones, a natural geologic formation from the planet Kadril, in place of crystals. These stones boasted numerous practical applications in medicine and communications; however, when added to other focusing crystals, they produced a broader beam." Star Wars Extended Universe Lore (SWEUL)
"For millennia, the Jedi Order lit lightsabers in every color and hue imaginable. However, following the Battle of Ruusan, the hues of most available crystals had been limited to either blue or green. Lightsaber color crystals could also be compressed, resulting in a pulsating blade, or they could be unstable, resulting in a core which swirled and sparkled."
I hope these tidbits of information help.
