Is Repentance a Condition for Forgiveness, or Should We Forgive Unconditionally?

Luke 17:3-4 ties forgiveness to repentance: "If your brother sins, rebuke him, and if he repents, forgive him...and if he sins against you seven times in the day, and turns to you seven times, saying, 'I repent,' you must forgive him." So, is repentance a condition for forgiveness, or should we forgive people unconditionally? Unfortunately, scholars don't agree. There are two groups: One group says forgive whether people repent or not. This is known as unconditional forgiveness. Another group says forgive if people repent. This is known as conditional forgiveness. I am in this camp.
