Why is dr livesey afraid of the squire in Treasure Island?

Dr. Livesey is wary of Squire Trelawney primarily due to the squire's impulsive and adventurous nature, which can lead to reckless decisions. He recognizes that Trelawney’s enthusiasm for treasure hunting may overshadow caution, putting their expedition at risk. Livesey's concern stems from a desire to maintain a level-headed approach in contrast to the squire's more romanticized view of piracy and adventure.
