I can kind of sympathize with the "not wanting the responsibility" aspect, so I think I can relate with what Joan is saying. Surgery feels like I have less time to deal with complications. Like if I drop a pedicle or a ligature slips, the animal bleeds and dies. It's more immediate in my mind and I feel like I'm less able to deal with the consequences. In my experience (or at least in my head) most animals won't die immeduately after a couple doses of the wrong medication and I feel more able to deal with the outcome.
Now some of this is just down to my comfort level. In other words, I feel way more confident in my ability to pick the right meds at the right dose and the right fluid type and rate etc. Likewise if I pick the wrong meds or the wrong dose I'm more sure that I can fix the complications. I'm not a confident surgeon AT ALL so when things go wrong I don't feel equipped to deal with it.
I did a cystotomy a few months ago to remove bladder stones. Dog did great in recovery, went home that afternoon. I laid awake all damn night terrified that my suture line on the bladder wall was going to fail and she was going to start leaking urine into her abdomen. I check my spays repeatedly through the day cause I'm paranoid a ligature is going to slip and they're going to start bleeding post-op.
I can sympathize with it, too. I mean, I understand what other people are saying about being responsible for any case, not just a surgical case, but I do feel like the balance sorta tilts toward the veterinarian with surgery, whereas a medicine case ... hey, I just give the meds, it's up to the animal to respond to them. I think it's just nuances either way; in the end you're responsible for your patient, period, but I can get why someone would feel like surgery is 'more' responsible, even if technically it's not.
So I get it. Surgery can be intimidating to people. The flip side, though, is that 'cut to cure' is SUPER satisfying. It really rocks to take a very sick animal - a FB, a GDV, etc. - roll into surgery, roll out fixed, recover and go home in a day or two a happy, recovering animal, knowing that without your intervention that animal had a very poor chance of survival.
But TT's right - it's super early in the process to worry about it much. A lot of people go to vet school positive they want to be a surgeon and doing a 180, and other people go thinking they'll hate surgery and end up loving it. *shrug*
There are plenty of jobs out there where surgery is minimized, I think.
