Huh, that somehow reminds me of Crassus from Rome [1]
> The first ever Roman fire brigade was created by Crassus. Fires were almost a daily occurrence in Rome, and Crassus took advantage of the fact that Rome had no fire department, by creating his own brigade—500 men strong—which rushed to burning buildings at the first cry of alarm. Upon arriving at the scene, however, the firefighters did nothing while Crassus offered to buy the burning building from the distressed property owner, at a miserable price. If the owner agreed to sell the property, his men would put out the fire; if the owner refused, then they would simply let the structure burn to the ground. After buying many properties this way, he rebuilt them, and often leased the properties to their original owners or new tenants.
TLDR: Got over his skis and mad with power and money. Decides to invade Parthia. Gets wrecked by horse archers. That ends up being typical for Romans, but this was the first-ish time that happened. Some of those captured legionaries may have ended up in China, though it is unlikely.
Not going probably never even crossed his mind. Social status in Roman society was very strongly influenced by military success. He was a previously successful general.
Historically (with all the accuracy you get when you summarize all of history) raising an army and not leading it was effectively telling everyone that you should be replaced by whoever did lead it.
