While he's shown to have a strong connection with the other cats in BloodClan, it's not romantic love. He views them as allies and tools for achieving his goals. He might have a degree of respect or even loyalty towards them, but it's not based on affection.
It's important to note that Scourge's character arc is marked by growth and change. Throughout the series, he experiences moments of vulnerability and empathy, which hint at a potential for love. However, his violent past and the deeply ingrained pain he carries make it difficult for him to truly open up to anyone.
So, while Scourge might not actively "love" anyone in the traditional sense, there are nuances to his relationships with other cats that suggest a capacity for deeper emotions, even if those emotions are often buried beneath anger and pain.
