First of all, thanks for the video from the DnD makers.
After some thinking I came to this conclusion:
Alignment is a good idea in theory, but there will be problems when you apply it to characters.
- If you have realistic or complex characters it is often very hard to put an alignment on them. A crazy psycho killer can be nice to his friends and family. A law and order fanatic can have some crazy hobbies. Many people (both in reality and games or movies) are quite inconsistent. Sometimes they act one way and sometimes completely different.
- It is possible to make a character that has a specific alignment and is believable, but its not easy. If you put any alignment to the extreme the result can be quite ridiculous. Its good for some chars, but you don´t want all of them that way.
I have the feeling that sometimes JRPGs are better in presenting archetypical characters for an alignment than DnD does.
Being completely nuts seems to be the minimum requirement to be a villain in such games. some examples:
Trails of cold Steel: Being chaotic evil without eating babies or randomly killing everyone just because
A person stands in a beautiful landscape. He is plotting to start a war. He says something like: "Soon this place will be consumed by the flames of war. I hope I can watch and enjoy this spectacle because the highest form of beauty is the destruction of beauty."
Virgo vs the Zodiac: I think that counts as lawful evil without having contracts to sell your soul
The main char is like this:
- She calls herself holy queen and servant of purity.
- She is on a sacred mission to restore order and bring back a golden age.
- Everyone with a different opinion is a heretic who needs to be purged with steel and fire. It is obvious that she is right, everyone else is wrong and without the right leader (of course herself) everything will be a complete mess.
- She cooperates with everyone (including psycho killers) and commits lots of crimes for the mission, but she would kill everyone, including companions, if they stand between her and the mission.
- She may feel bad about it, but her sacred mission comes before everything else, including her own feelings or the life of any other creature,
