Depends. Is the person thinking of suicide right now or are they a complete asshole?
If the answer to BOTH of those is no then I wouldn't.
If the answer to one of them was yes then I would prep the calling card during the expedition.

What if it was someone close to you? In That case for me it would depend on what they are doing.

I agree with @Firematthew if it could help people and bring justice to bad people then yes. I would trigger a change of heart for the better.

Yes. There are too many scumbags in this world that need one.

And if it was someone close to me, if they are doing bad things or have suicidal thoughts, yes, if it could help them, I would do it.

Yeah same tho I'd try to get them to stop what they are doing before talking that step.

Taking*

I think I covered that under "complete asshole" and "suicidal thoughts" @JokerXV. Though I would do my research on a person before I actually did a change of heart... irregardless of the type of person.

True steps would need to be taken first tho I'd say it really depends on the situation.

I'm gonna say it again, there are some terrible dictators in the world who need a change of heart. And no, not Donald Trump, that joke was never funny.

I'm not sure. I agree it would be nice to have the bad guys confess. But I can't justify it unless it's a really big deal.

For me, its all about if it helps people, if people are suffering, than I think a change of heart should happen

Yeah honestly if it was to help people I think that is what would push me to do it.

I'm a firm believer in doing something with your own power. So if I could, I'd only do it after I tried to the best of my normal extent.

So last resort? Hmm it would be tough unless you the person are in that situation.

I'm the type of guy who is there through thick and thin for his friends, so it'd be one in the same. I understand what you mean, acting on your own power while another party suffers, it you have a quick fix you should use that.

If it helps in the end then maybe it would be the right call.

Like I said, if it helps people, a change of heart should happen. Many people are silenced from speaking up against people who abuse them, for example, the volleyball team of shujin. Of course research is necessary to find out what exactly it is they are doing. There should be a justified reason before a change of heart though. It should not just be on instinct, but if it is the right call, and it can help people, then a change of heart should occur.
