Maybe I do not find chronicles about morbid humour but I can find plenty about (apparently) unnecessary cruelty and massacring the (apparent) innocents. As we were on Mehmed, here's on from the conquest of Otranto in 1480 (at the end of his reign, but not an army led by him):
There was in Otranto a bishop of irreproachable conduct and old age. These savage barbarians, the Turks (more like dogs than humans one might say) subjected this man to a most horrible death, without consideration of his dignity or his age, without any pity or fear of God, whatsoever. They impaled his body from his groin all the way to his head so that his entrails were completely pushed out of the body.
or if you want deeds ordered by him, check Doukas's accounts where he massacred some peasants in 1452 because they dared to complain that the construction work at Rumelihisarı ruins their lands. The story with the Venetian merchant ship whose captain was impaled and crew massacred is also told by Doukas.
Oh, and on Vlad sources do not tend to portray him as a monster, only a selection of them does. If you just pick Ottoman sources you'll certainly see him as a monster. If you get a mixed bunch of Ottoman, Byzantine, Slavonic, German, Italian, etc. sources you'll get a much more complex character and many stories of cruelty are not confirmed or told in a different manner by other sources. Also many sources are distorted in the popularization of the historical character Vlad. It is usually told that a Slavonic chronicle testified for him torturing small animals in his prison from Buda but it is not told that the same source also testifies that his cruelty in his country was directed at villains, no matter if rich and poor, and that the people became so honest in Wallachia that on a fountain's edge was a golden cup every traveller used to drink water with it but no one dared to steal it. It is usually told he mutilated women's genitals but it's not told that this was the punishment for adultery. If the sources are misread, the picture gets fatally incomplete.
