You'll also find some decent warrior-related equipment as you complete the main and side quests.
Similarly, it is asked, are the Companions good Skyrim?
The companions aren't evil, they may be cursed and revel in it, but they're mostly decent people, their sidequests are largely about helping people in need. Thieves Guild are amoral for the most part but not completely evil.
