According to Osho, considering both sides as friends means holding goodwill and concern for all participants—no enmity—while refusing indifference or fake neutrality. Friendship demands a stand: support the side aligned with dharma (truth/right), yet remain compassionate toward the other. Thus you can be divided in support, not in love: act decisively, but keep an inclusive heart.
Be kind to everyone, but still choose and help what you feel is right.
