Can a person also be a tool?

In philosophy, the tool definition of something that can be used by humans to perform a given task, i.e., a hammer, screwdriver, knife, a pair of pliers, etc. <br><br>Mostly, I am thinking of someone who has held a position of power, and has used that position for the betterment of society, and a lot of people believe this person is above the criticism. For example, someone like MLK, and particularly Jesus of Nazareth, who went out of their way to perform political activism. In this way, they are powerful tools. <br><br>Further, it would seem that to see other people as tools, is a harmful way of thinking and seeing the world. To see them as values that can be used to lessen a burden, or provide some utility. It is almost a form of narcissism, and a form of dehumanization, by viewing people as a tool. <br><br>On the other hand, there is a long history of people using themselves as tools. I believe it was Foucault who said that the self must be worked on and shaped, like a tool. But the self can also be a tool for others to use. With this comes the problem of consent; do you consent to being a tool for other people?
