Bloodthirstiest → It is formed from "blood" (from Old English "blōd", meaning the red liquid that circulates in the body) and "thirsty" (from Old English "þirstig", meaning having a strong desire for something). The suffix "-est" indicates the superlative form, meaning the most. Thus, "bloodthirstiest" describes someone who has the strongest desire for blood or violence.
Think of someone who has a strong 'desire' ('thirsty') for 'blood' — that's why bloodthirstiest means having the most intense craving for blood.
