is ROTC unethical?

i kinda want to join ROTC, but i dont like what it stands for. even if i never do anything with my armed forces skills, it would still be supporting a violent association. on the other hand, i would enjoy learning the values and skills they teach during the schoolday. you would probably meet alot of devoted people there too, in stead of in marching band when they're just there to screw around. it would probably be alot less expensive too. its a good thing i dont have that option since ive already signed up and started paying the fees for marching band.
