Hmm, about Ioannes' personality, how about this?

Stockholm Syndrome is encouraged in the Giray Slave System, and said Syndrome can be encouraged by acts of kindness on part of the captors. Therefore, Ioannes values kindness because he's latched on any kind acts shown to him during his time as a slave, and later on wants to be kind himself, because that's how he's been treated, even if it has been just to get his allegiance.
