What to say? I'm a bad person but to be serious my comment wasn't "cruel" per se, Reborn is not impossible (i always won without help and there are many people here far better than me at this game) and if you're having problems with a Puzzle/Trainer/Gym Leader (pick yours) there's always the forum to help you, if after all this help the person is still complaining then Reborn is not for them (just like Dark Souls is not for everyone), it's as simple as that.
P.S.
Fern is bad and that's all there is to say...ok from what you felt "good" in him? He doesn't care about his sister he cares about his "family pride" and let me tell you a secret: if a person joins a terrorist group voluntarily (and i have no reason to believe it's not) then that person probably is...well...not good
