They are generally the strongest but not necessarily the worst. The two deadliest tornadoes on record ocurred in Bangladesh. The tornadoes in Bangladesh are not necessarily stronger than thoese in the United States, but the lack of a warning system, high population density, poor construction methods, and a high rate of poverty in Bangladesh excacerbate the effects of natural disasters such as tornadoes.

Tornadoes are called a thunderstorm's worst killer.
This cannot be answered simply, as both hurricanes and tornadoes vary greatly in how bad they are. The impacts of both tornadoes and hurricanes can range from negligible to devastating. That said, the very worst hurricanes can be far deadlier and more destructive than the worst tornadoes.
Yes. The destruction caused by the worst tornadoes is often front page news.
Generally yes. F5 is the strongest category of tornado capable of completely obliterating well built structures. However how bad a tornado is depends on factors other than strength, such as where the tornado hits. For example, a number of F5 tornadoes have traveled over open country, with the worst damage limited to farms that were destroyed. A list of the worst tornadoes in U.S. history will consist mostly of F5 or EF5 tornadoes (including the #1 worst), but several F4 tornadoes would be on that list as well.
It varies. Most tornadoes don't kill anyone. At their worst tornadoes can kill hundreds. The highest death toll for a single tornado is 1300
