I agree with @MrsSkylerWhite- if they said "you look like a nice person" I'd just say 'I'm not.' And as for 'do you want people to die,' I might say 'yes, to decrease the world's surplus population!!'
'......do you want people to die???' 
WOW, I haven't had anyone say this to me... (do you want people to die?!) That is dreadful. But I can believe someone would have said it. Some guy approached me and DH once (about 4 years ago,) trying to raise money for an animal charity, and he said 'morning people! Do you like animals?' (FFS Who doesn't like animals?
)
DH was in a bad mood that morning (not with me but just a bit salty in general,) and he said 'mmm yeah I do. Labrador on toast is particularly delicious!' and gave the man this look >>>
The man said 'oh ha ha very funny.' And gave him the look back...
Prick.
As a pp said (@historyrepeatz ) these people don't give a shit about what they're promoting, it could be a charity one day and an energy company the next. They're just doing it for the money. A friend of DD's had a short stint working as a chugger some 5 years ago, when she was at uni, as she needed the money. Only lasted 3 weeks as she HATED it, and the horrible manipulative tactics they used.
But also, she said she got paid £75 for every person she signed up!!! £75! They don't want one-off donations like they USED to want/ask for ... The whole idea, is for them to get peoples bank details so they can push more stuff on them to pay up for, and just take it out of their bank account, as per my post way back in the thread... Nasty manipulative behaviour.

And whilst me, and DH, and most people on this thread won't tolerate it, and will notice anything extra coming out of their bank account, some people are much more shy and nervous and awkward and are afraid to say no, and some may not notice extra bits and bobs coming out of their bank account...
As has been said, these chuggers are DREADFUL and need banning.
