Prepare an ice-water bath; set aside. Put eggs into a medium saucepan, and cover with cold water. Bring to a boil. Remove from heat. Cover; let stand 12 minutes.Using a slotted spoon, transfer eggs to ice-water bath.
When eggs are cool, peel, and cut in half lengthwise. Carefully remove yolks, keeping whites intact and transferring whites and yolks to separate bowls. Refrigerate whites.
Add roasted peppers, mayonnaise, mustard, salt, pepper, paprika, cayenne, and hot sauce (if desired) to yolks. Mash with a fork until smooth. Cover, and refrigerate until stiff, about 30 minutes.
Mound yolk mixture in each egg-white half. Garnish with bell pepper, scallions, and chives to make devilish faces.
