After killing Prince Adolf, Abel took all the items he looted into his personal storage box. Since Prince Adolf was such an important figure, he didn't dare to have a good look at them when he was inside the Double Moon Forest. These items might have a tracker on them, so there may be a chance that someone could figure out his whereabouts.
Abel knew how frightening Grand Duke Edwina could be. From that alone, he could tell how strong Grand Duke Francisco must be. To be honest, Even Wizard Cliff couldn't be compared to those two right here.
Just to be safe, Abel did hide away Arvid's corpse at the time. He wasn't sure if this was going to slow down those who were trying to find him, but if anyone was trying to look for Arvid, it would most likely take them forever to do it.
