Orochimaru did love before Tsunade lost Dan. He loved Tsunade and Jiraiya and his parents. But Orocihmaru was a little mentally unstable. After watching various people suffer from their loved ones dying, he tried to find a way to live forever fearing death. His is the original Normal Ninja goes power hungry crazy. Sasuke being his successor in that department.

I think after all the nonsense that happened with Sasuke, he finally mellowed out. He isn't a selfless person, but he can care for those he holds dear like his 2 sons.
