Worried my brother might be a pred

during my senior year last year, my older brother (in his 30's) was the one taking me to and from school most days cause our mom couldn't and didn't want to. there were a few instances where he would pick me up, and make comments on students like "they're cute" or "I hope they're 18 and if not they need to hurry and be" maybe not exactly those phrases, but things along the lines of that. i would always just kinda laughed it off, cause it really rubbed me the wrong way. i was 17 my entire senior year, so still a minor, and he felt comfortable to say those things about people my age. he's never actually done anything to any kid, and when i was younger getting groomed online he stepped in and told me to block them cause "pedophiles are bad people", so i dont wanna say that hes outright a creep and a predator but i cant look past that and i dont know how to feel. i really dont want him to be one cause i'm about to move in with him since we just escaped our abusive household. but he has basically no friends, no relationship with our parents or family, and has a lot of trauma so i dont know if hes going through something mental or what. but im still grossed out by it. and also sometimes when we're talking or if hes complimenting me on something like my hair or outfit or whatever, the words like "cutie" or "my love" will come out, but i really dont think he means it in that way. i really hope he doesnt. maybe thats just the way he talks and expresses affection? idk..
