5e allows you to play any of the nine alignments. Most players that I've met tend not to play evil alignments and the ones that do usually end up alienating themselves from the party but there's no game mechanics preventing it.

We play on a website called Roll20.net because I'm in OR, my cousin is in Tacoma, WA, we have a married couple that play with us in Seattle, another married couple in OK, and the last guy is also in OK. The Roll 20 site gives us a means to all play together on a virtual map with virtual dice rolls and everything. It's not as much fun as sitting around a table and rolling real dice together, but it sure beats not playing at all and it's still a blast.
