How about something for shadowrun?
Martyr
You care enough for others that you will die for them. You can’t allow another to suffer in your place, and choose to suffer in the place of others. You follow a spirit who cares about others, you, and the whole universe. Following this spirit can cause difficulties as you begin to care for even your enemies like they are your neighbors.
Advantages
All: +3 to assist attempts when you are not the lead on the check
Magician: +3 to all health spells used on others
Adept: gain Empathic Healing (Street Grimoire) as a bonus power
Disadvantages
A martyr is unable to kill unless he/she has to. When you attempt to deliver a killing blow to a person, you must make a successful Charisma+Willpower (3) test. On a failure, your attack misses. This is determined after damage is calculated.
