Dominate power: how would you rule a suicidal order?

[Zulgyan]

Dominate
Fatiguing, Concentration
You can mentally control another creature’s actions. The target makes a
Will saving throw. If the save fails, you control the target’s actions. You
can force the subject to perform any action you wish, within the limits of
his abilities. You’re aware of what the subject experiences via your mental
link, but you do not receive direct sensory impressions from him. Subjects
forced to take actions against their nature receive a new saving throw with
a bonus of +1 to +4, depending on the nature of action. A successful save
breaks your control.
Special: You must be in mental contact with the subject.
Time: Dominate is a full-round action.

How would you rule an order like: "jump into de cliff" or "cut your throat".
Do you think this orders should ever be allowed?

I'd allow it.

Since I'm playing Blue Rose, I'd rule that the target had a +4 bonus to the saving throw, the arcanist would have to make a DC 20+ Corruption check.

If I was playing True20, I'd still allow it. Honestly, it's not much different than having your expert buddy cut the throat of someone you are psychically grappling. (Heck, one less arcana check to psychically grapple...)

I would make it hard to do since that is doing something that the person is VERY opposed to do and make it an easy save for the person to fight off.

Will +4.

Villians and Heroes are sure to spend convicition like it's going out of fashion if they fail.

Minions, who cares...
