You did it quietly because the Big Mom gave you the fake documents so that you wouldn't get caught by the guards because they don’t know who you are.
(In fact - I have already done a very big post about that the reputation mechanic in LonaRPG sometimes is very strange and illogical)
Yeaaaah... i said about it very long time ago that If you kill your horse companion deep in the forest then you lose your reputation while if this horse dies by itself from monsters then you do not lose reputation. Why? Amm... am... ammmMMMmmMm? I don't know~ maybe because there was something like GPS navigator on that horse and when the horse dies it sends a signal right to Milo himself that you killed the horse;)
One of the funniest things I’ve found about reputation that if you have a cannibal skill then you can gather meat from the dead human/humanoid bodies and if you have a 10 SUR stat then you can cook smoked meat.
2 human meat = 1 human smoked meat
1 human smoked meat = 150 TP
10 human smoked meat = 1500 TP (Almost 1 Big Copper Coin)
...which means you can trade it to make a good money or... you know... maybeee... raise your reputation with moneeey?
I think you already understand where this is going?;)
Yep... for example - you can make a real massacre in the church and then collect the meat from all killed people and then sell the fried meat of these church people in the same church to earn a positive reputation = there are no consequences of being a total maniac~
