These are the jungle version of leopards the least pleasant of the big cats. Moody bastards.

My leopard story

My sister is married to a ranger in South Africa. She saw a leopard with a fresh kill by a waterhole. A whole troop of baboons attacked it. Although out numbered it didn't just surrender its kill. It stood its ground hissing and slashing until it was surrounded and they rushed it. It sprang into the air and escaped over their backs.

Unlike other cats it did not forget about it and get on with things but bore a deep grudge against these baboons, if it found one isolated it would lie in ambush and attack. It killed a few females and babies. These kills were not to eat the baboon, as it would not have time to eat before the baboon troop would organize and attack it, but plain meanness.
It saved its deepest hate for the biggest Alpha baboon. As time went on my sister would see the Alpha male grow more battle scarred. The leopard would wait for him to be isolated and then run for him and slash at his face. The baboon troop eventually began avoiding that area.

She has a few tales of this nasty cat. Once she saw it in a ditch by the track, on its belly. Walking towards the track she saw the baboon troop. She waited to see what would happen. The Baboons veered off slightly and this took them out of the leopards sprint range, so it got up sprinted low behind the wagon, raced ahead of the baboons, slunk low and waited for them again. This time they turned around and began to head back. This all took nearly an hour. The leopard returned to the ditch to wait. Unfortunately my sis could not spend all day watching and had to get on, but its was an illustration of how much time and effort this particular cat would spend for in daylight for no real return other than slashing at the baboons, time that would be much better spent hunting prey it could eat.
