You worked for Doctor Eggman, mostly on mechanics, fixing robots and machines. Working for Doctor Eggman for others may be deemed evil, but you needed a place to live. You needed to survive. So if you have to take dire measures to avoid poverty then so be it.
You didn't really know what happened outside of the base, you were always inside. You werent super shut out though. You understood that Eggman hated Sonic and his friends. Hed always come back with broken robots for you to fix and to talk about how horrible Sonic is. It was an earsore but you listened.
Eggman came in one day with someone new. You continued your work as usual not really caring. You had overheard the new guy's name was Doctor Starline. Eggman was giving him a tour and when they got to where you were working he was in awe.
"Oh my! It's all so lovely!" Starline said, as if Eggman was his idol. This guy even looked a bit like a freak. What was that hairstyle? And the way he carried himself. You worked for Eggman, that didn't mean you idolized him. He was a genius of course, but no match for Sonic, not that much of a genius, that was proven by all the broken robots you had to prepare.
"And you must work here too!" He clapped his hands together. "You must be always busy fixing those robots. Enlighten me er, name? I'm Doctor Starline!"
An Eggman fanboy alright.
