Jack raids Ralph's camp because he wants complete control over the group and is envious of Ralph's leadership. He sees Ralph as a threat to his power and believes that by stealing resources and asserting authority through fear and intimidation, he can establish himself as the sole leader.
It's because they don't have Piggy's glasses with which to start the fire.
Piggy's glasses
In chapter 10: the Shell and the Glasses Jack informs his tribe, and I quote, "But tomorrow we'll hunt and when we've got meat we'll have a feast---" Bill then puts up his hand and asks, "What'll we use for lighting the fire?" Jack blushed but then informed his tribe that, "We'll take fire from the others." Eventually Jack did set out, with Roger and Maurice, to raid Ralph's camp, not for fire but for the means by which fire could be made, namely Piggy's glasses.
Jack and his hunters go to Ralph's camp to steal the fire because they believe they need it for their own safety and to cook their food. Additionally, Jack wants to assert his power and control over the group by taking something that is essential for their survival.

Jack
The hunters raid Ralph's group because they want power, control, and dominance over the other boys on the island. They are attracted to Jack's leadership and the promise of hunting and violence, which appeals to their primal instincts. This leads to a power struggle and conflict between Ralph's group, focused on civilization and order, and Jack's group, focused on savagery and chaos.
