Marko made sure to look after his people and raise them correctly, teaching them that the most important aspect in the world they live in is to do what it takes to survive, he taught them to look within their selves and trust their own instincts. Due to his brother’s age 8-years-old, Sergio was planned to be sold as a sex slave. SG2K: Marko was always meant to be on a steady Westward trek that would eventually lead to a collision with the Courier.
All the while having to listen to Dickey’s laughs of pleasure to his suffering, the only thing that kept Marko going was thinking about Sergio’s happiness. Believing that after all the things he had witnessed, such as towns eating people and places where kids are killed for stealing food, 'right and wrong' morals are delusional and self-indulgent. It wasn’t long later that he heard the Courier killed Sergio, this fuelled Marko’s rage and decided to postpone his retirement, setting his plan to take down the Courier to a higher priority.
