Actually, some team members had been complaining about the long journey since the start, and frequently displayed attitudes that suggested they wanted to go back, so the leader already knew that there were some inappropriate thoughts among some people in the squad.
Just as those team members said, he indeed purposefully avoided some high-reward missions when selecting tasks because the people posting the missions weren't fools; simple tasks wouldn't offer high rewards.
The missions he chose might not pay very well, but after the mission was completed, the share each person received actually wasn't too little, especially since the cut he took was ten percent less than other squad leaders.
Besides, they didn't consider that although other squads' members had lower share percentages, they still received high payouts because fewer survivors were left at the end of the missions.
