Nah, i wouldn't want to live forever for starters, and taking the lives of 5 people i cared about wouldn't cut it.
Bonus 1: imortality, i would literally become a super hero fighting for good, but i could imagine my methods of fighting crime in the uk would probably get me into serious moral dilema and would question whether what i was doing was actually good, so ill have to pass, if i was gona cchieve imortality i want it temporarily.
Bonus 2: No, remotely would make it worse! making it remote is just a buffer to yourself from resposability, and if you going to live forever and be imortal, you need to start that kind of journey with a strong grasp of responsability. shying away from such a thing is weak in my eyes.
Bonus 3: I still wouldn't do it. Those 50 to 100 random people could end up being people that have no effect on my life, people who are terminally ill or anyone else, but it's not my right to descide if those people die. if there's even the slightest chance i could cause the death of someone like a doctor, freedom fighter, musician or politican who brings hope and happiness to hundreds of people, in return for my own imortality, i would rather die.
