Tentative Answer - Marx and the Morality of the Classes

2. Are the bourgeoisie evil for Marx? Are the proletariat good?

I don't believe that Marx's philosophy on capitalism and labor really even addresses whether or not the bourgeoisie are evil or whether the proletariat are good. For Marx, the root of evil lies in the system of capitalism because it requires individuals to sell their labor in such a way that demeans and devalues them as persons. While the bourgeoisie plays into that system and takes advantage of capitalism in such a way that places them in a better economic system at the expense of the proletariat, Marx doesn't seem to weigh in on the inherent good or evil qualities of the bourgeoisie  or the proletariat.

With that said, the bourgeoisie does take advantage of capitalism in such a way that forces the proletariat to sell their labor in a way that diminishes their value as humans - playing into such an exploitative appears to be an "evil" action. Marx's solution to this practice of exploitation and playing into the system of capitalism was a total class struggle that ends with the proletariat rising up as one and removing the system of capitalism itself from society, thus removing the class barriers and exploitative systems that oppress the proletariat. Again, while this appears to be a "good" action on the part of the proletariat, Marx argues that this is just the inevitable result of capitalism, as a catalyst for social change and the development of class consciousness ultimately manifesting into total class struggle.
