He is monetising mental health - how can that not leave a bad taste.
He is in this for himself, and himself alone. I believed he was after an easy (comparatively) lucrative career as a telly doctor as soon as he was revealed as a medical doctor on Love Island. If he was simply trying to improve mental health on the national health he wouldn't be doing the other stuff, the influencer ads, the comped holidays and experiences the begging for freebies for expensive things that other medics and mental health professionals pay for themselves from their salary, selling his bath bombs (is he angling for a spot of the apprentice?) and sliding into 19 / 20 year old women's DM's. He is a wolf in sheep's clothing.
Loosing a family member, and such a young one is absolutely heart wrenching, but it is not a free pass in life to act as he does using people (his auidence, vulnerable people suffering with their own mental health, his ex, random women etc) and it doesn't suddenly make him a good guy. He is who he is.
