No I can't, because that's not what I'm claiming. Mechanics wise they're mostly identical.

My guess is that the staff have realized that without the "perks" to being good-aligned that nobody would play good-aligned characters, for all the reasons mentioned elsewhere in this thread.

As a side note, another reason (besides having fewer targets) that goodies don't get as many kills is that the targets they do have are typically of a higher average skill than the set of targets available to an evil character. So not only are there fewer people to kill, the set of people you can kill is going to consist of a higher-than-normal percentage of vets.

One other thought on the stats you posted:

Kostyan, Djabree and Khargurln managed to accumulate those goodie kill counts while also killing a ton of neutrals and evils. Had they decided to concentrate solely on killing goodies then I would expect their goodie kill counts to be slightly higher. Djabree, for instance, was focused on killing mages, then members of Empire and Scion, all of whom are evil.

Here's an expanded list with the top 15 for each alignment in terms of total PK wins, in order of total PK wins, with number of "opposite align" kills listed:

Evil:

Kostyan, 174
Djabree, 95
Blitzenturt, 223
Hunsobo, 241
Igbah, 173
Kharghurln, 183
Ravon, 158
Kjrorh, 112
Nreisshe, 122
Vens, 94
Kanaev, 122
Grunlath, 139
Dulmisa, 130
Cabdru, 112
Palmer, 75

High: 241, Low: 75, Median: 130

Macha, 109
Niheriva, 150
Alriac, 119
Malthalia, 70
Gryshilniar, 110
Hyzin, 121
Jeqo, 81
Brinton, 111
Mizfara, 103
Darascus, 95
Mhardat, 57
Obaznuk, 83
Lariya, 83
Adhelard, 83
Dungard, 79

High: 150, Low: 57, Median: 95

And, like I said, if those evil characters had been concentrating on killing only good-aligned opponents then their goodie kill totals would be even higher. (At the expense of their overall kill totals, of course.)
