As a convinced idler I've long thought this is the case; this was a reflection on my own flaws prompted by my strong belief that significant presentations in other people of what in the old days would be called "weak character",eg obesity must be majorly down to underlying mental disorders or weaknesses because nobody would choose to be like that, right?

The neural or mental cause hypothesis for the latter has been pretty much proven by the success of drugs like Ozempic; it's really not a great stretch to see other deadly sins as similarly significantly brain-derived in addition to (and possibly sometimes dominating) environmental and cultural influences.

The important thing though - if you believe this - is not to claim victimhood as a sufferer but to grasp the opportunity that comes from identifying a challenge, and investigating the tools and techniques available to counter and - with perseverance - defeat it.
