Including Roland, the vast majority believed that starting a battle with three members of the Seven Deadly Sins at the same time would inevitably lead to an incredibly intense fight.
Judging from the Seven Deadly Sins' battle record so far, this seems like a safe bet. Wherever those guys go, it's always a sea of corpses and blood with scorched earth all around. Even if sometimes it's not intentional, their power is so overwhelmingly strong that it's easy for them to inadvertently destroy the surroundings.
Gathering three such individuals and not making it a scene of heavenly upheaval and thunderstorm would seem quite unreasonable.
But the battle with Sloth and the others was incredibly "quiet."
The air at low orbit is extremely thin, almost indistinguishable from true vacuum, so no one can hear screams or explosions. But more disconcerting than the physical quiet was another kind of quiet that even the usually calm and collected Roland found unsettling.
