Live feeding my bp?

Hi guys! I got my ball python about 3 ish years ago from a local, humane pet store. When i got him, when he was a baby, i was advised to live feed him by the owners of the pet store. For 2 years i fed him one live mouse a week as he would take it (he had a 6 month hunger strike, saw a vet and it was fixed!). Since then ive been feeding him 2 live mice every two-three weeks in a separate enclosure and I havent had any problems with mice injuring him or attacking. Yesterday I saw a tiktok about live feeding and how it can be hurtful for the snake and have been having some doubts about live feeding him. Is live feeding really as bad as people say and should i be feeding him frozen? Is live feeding him the wrong choice? I would never want to put Sam in any danger and I only want the best for him. Please let me know what you guys feed your ball pythons and what i should be doing with Sam!
