The Stranger - careless or evil?

The further I read into this book, the more appalled I am by the way the main Character acts. I already knew that nothing really mattered to him; I did not realize, however, that if a person does not care about anything, then they basically have no morals. Meursault just does things that he is asked to do or wants to do without even considering that it is wrong or hurtful to others. It goes to the extent of him helping out his new friend Raymond to commit domestic abuse to his girlfriend. This really made me aware of the amount of awareness and passion it takes to truly make the right decision.
