Hard to say. Pre-Boruto, I am sure he didn't love anyone. Even when he became ally to Konoha, he had a pretty neutral stance. But now, it seems kinda vague - he's still as manipulative as ever, but there's also that one line where he said he didn't want to erase Mitsuki's memories again that showed he has some affection for his progeny.
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.
ANBU are a group of elite ninja who are directly under the village Kage that carry out special tasks. Root is a sect within Konoha's ANBU who are loyal to Danzo and take orders from him, even if they conflict with the Hokage's wishes.
