You should not have difficulties to find a nice Nullsec corp. Living in Nullsec is not that hard or dangerous as it seems. I personally feel much saver in Nullsec just for the fact that if someone enters Local, i know exactly if that guy is a friend or will try to hunt/shoot me. I allways get a bit paranoid in High-Sec if i have a catalyst lurking arround somewhere near me and can’t do something against it
If you are interrested trying out NPC 0, i could recommend you I-Red (Ishuk-Raata Enforcement Directive) in Syndicate for example. Cool bunch of guys with the right attitude to the game.
Just don’t be afraid to get your feets wet. Try out some alliances / corps and if it doesn’t fit your playstyle, try another one until you find your place. If you have more questions, feel free to contact me ingame.
