I chose mage because I love magic.

Honestly, being a Witcher in it of itself is cool if you could live with the cons of being a Witcher,

If I was a Witcher, I’d just enjoy the benefits like superhuman strength, speed, the senses, Signs, etc. There’s nothing forcing me to actually hunt monsters.

@Atlas D. Aeradon the issue isn't so much not having to hunt monsters as it is the fact that most of society shuns them, treating them with disdain and contempt to the point many wouldn't be able to find work doing anything else (unless you count assassins like the Cat School). A witcher might be able to settle down for a solitary life (like as a farmer maybe) but there's a reason you hardly see any witchers in other professions outside of ones that require killing.

@Mechemik I don’t know what you’re getting at, but ok.

@Atlas D. Aeradon witchers still need to eat to survive. Food costs money. So unless you're a farmer witcher, you're going to need to make money to survive, even if just to buy food. And as most of society shuns witchers (Nilfgaard even goes as far as banning them from entering cities) your job occupations are very limited. Lambert also remarks on this/why he's so bitter about his lot in life (he still walks the Path because he can't really do anything else). So while you may go "well nothing is forcing me to hunt monsters" the fact is, there's a reason you don't see many witchers in occupations that don't involve just that. Basically, the odds are not in your favor to do something other than killing monsters or mercenary work when society is prejudiced against you.
