"Being muscular doesn't mean you're indestructible and have no fears (or even feeling insecure)"
Yes that's obvious, but I'm talking about his character design and how it contradicts who he is. Also his character, based on dialog, does indeed portrays signs of insecurities.
"He's not a scaredy cat either tho"
Cowering in fear under the table and having a panic attack over talk about ghost and disappearances, scared of the dark, going in an abandoned church and so on and so forth does make him one.
"Muscles won't protect you from ghosts"
Again not talking about ghost talking about who he is. Went a bit more in depth in a previous reply, I'll just add that his previous one made it more believable to be the way he is then this one. Was it perfect? Not precisely but it did do a better job
