Which word describes someone accompanied by or eager for bloodshed?

The term that best describes someone who is accompanied by or eager for bloodshed is "sanguinary." This word is derived from the Latin "sanguis," meaning "blood," and it conveys a sense of an individual who is bloodthirsty or inclined toward violence. In contexts where bloodshed is a prominent theme, "sanguinary" effectively captures the essence of someone with a penchant for brutality or who revels in killing.

In contrast, the other terms do not align with this specific meaning. "Raconteur" refers to someone who tells stories or anecdotes in an entertaining manner, which is unrelated to violence or bloodshed. "Quixotic" describes a person who is exceedingly idealistic or romantic, often in a way that is impractical, focusing more on dreams than on any inclination towards aggression. "Redoubtable" denotes someone who inspires fear or respect, particularly in a formidable or intimidating manner, but it does not inherently express a desire for bloodshed or violence. Therefore, "sanguinary" is the most fitting choice in this context.
