But with it, I have to put the annoying \justify on each paragraph (at least when I use itemize).
There is away to justify all the slides with only ONE command, for example, in the preamble?

As I said, these are untested, but the general idea should set you on a course. I don't know if this is what you want, let's just hope it helps you somehow.
The previous code solved the justification issue. However, it "disables" the center environment. Why? It just a doubt, I use the centering command to center my images, but I'm wondering why the center environment is useless.
