Eckels' personality is one of a thrill-seeking, experienced hunter who craves new challenges. While his treatment of others is not specified, his boastful nature may influence how others perceive him, either positively or negatively.
Step-by-step explanation:
Based on Eckels' statement that he has hunted various large game and seeks to now hunt something which he refers to as 'it,' we can infer several characteristics about Eckels' personality. He appears to be an experienced and adventurous hunter who seeks new and more challenging experiences. This shows him as someone who craves thrills and possibly has a disregard for the dangers involved, both to himself and to others, if his thrill-seeking leads to irresponsible behavior. Moreover, a tendency to boast about past conquests may indicate a measure of arrogance or a desire for recognition and esteem from others.
Eckels' treatment of others is not directly mentioned in the quoted statement, but we can hypothesize that someone with his characteristics might treat others as either comrades in adventure or as spectators to his prowess. Depending on how he expresses his adventures and achievements, he could either inspire admiration or foster resentment among his peers.
