How is prejudice to the vulnerable evident in Lord of the Flies?

Prejudice against vulnerable individuals is illustrated by the way Jack and his hunters treat Piggy, Simon, and the littluns. Both Piggy and Simon are vulnerable because they are viewed as outcasts among the group of boys and are easily intimidated by Jack and his hunters. Piggy is overweight, asthmatic, and easily frightened by Jack. Similar to the littluns, Piggy relies on Ralph's protection to survive. Simon is vulnerable because he is known to faint and is considered extremely weird by the group of boys. Simon also has difficulty expressing his feelings, which is one reason he is ridiculed and overlooked. The littluns are not only physically weak but are too young to challenge Jack and his hunters, and they cannot make rational decisions without the help of Ralph and Piggy.
Jack and his hunters continually taunt Piggy, interrupt him during assemblies, and physically threaten him. They understand that Piggy is too weak and afraid to defend himself, which makes him an easy target. Piggy is bullied by the other boys and only becomes close with Ralph after Jack establishes his own tribe of savages. Similarly, Simon is neglected by the group of boys and is labeled an outcast because of his odd behavior. The boys rarely listen to Simon, and he becomes an afterthought among the group. The littluns are essentially left to fend for themselves as Jack demonstrates his lack of sympathy when they cry at night. Unfortunately, Piggy, Simon, and the littlun with the mulberry-colored birthmark lose their lives on the island because they are vulnerable.
