Few ideas:
1. Give us some 'protect citizen' spell which will make citizens considerably
harder to kill. (maybe grants us little conduct or maybe not, i don't care)
2. Some system where we could get conduct for killing those who keep raping
the batcity citizens (maybe 0,0000001% of conduct or so) or just permission to
kill them.
3. Possibility to call cityguards/knights to defend the citizen
Hmm, some of these ideas don't seem very civilized but when speaking doesn't
help, you must bring in more radical ways...
Asking for 0.0000001% of conduct for killing someone is stupid. Do you realise
you will need to kill 10 million people before you get 1% of conduct. Why do
you even suggest that number:P
