Pros and cons of isted suicide?

I'm working on a lincoln-douglas debate. My resolution. 'isted suicide ought to be legalized' I'm on the negative side of this debate. My three contentions are -sanctity of life, -universal way of life, & -taking away from sanctity of life. << When I use sanctity of life as a contention... I'm finding very little info. If anyone could help find some, or tell me what they think about this whole debate. Thank you so much.
