opinions on tail rot/vet….

(i put graphic just in case, im not 100% on what this would be considered)

my brothers leo got tail rot and we took him to the vet where they said to soak him 2X a day and if it doesn’t fall off call back. we’ve been soaking him but his tail has been like this for a few months and he just won’t drop it. he was on meds in the beginning and we stoped when it instructed us to. he seems fine, he’s eating good, drinking and active. we called today to schedule the tail removal, they basically told us it’s up to us if we wanna remove it. they either sedate him and take it off or we leave it and it’s “dead weight”. we asked if the sedation was safe and they didn’t sound so sure about it. does anyone have experience with something like this? we don’t wanna have him sedated and he doesn’t wake up but i also don’t wanna keep his tail on if it’ll hurt him eventually. 3rd picture was back in october and the first 2 are today. any advice is appreciated.
