Yeah. That is the point of many characters in many franchises and trilogies, eg. Ramsey Bolton is civilised but also a complete psychopath and borderline sadist
Point is is that there is more expected from a ‘lord’ or ‘king’ like Stannis than a wildling like Craster...that’s why I believe Stannis was the worst father cause he should’ve ‘known better’ than Craster...if they were siblings or had the same rank bestowed upon them then yes I would agree that Craster’s actions were worse
Stannis killed one daughter, Craster killed crazy amounts of sons and raped crazy amounts of daughters, Stannis actually loved his daughter, even if he loved her less than his military campaign. Craster showed no love or compassion at all.
