Finally, everyone can decide for themselves if they want/should buy Soda or not.

Soft drinks – hard facts Should German schools be allowed to offer soft drinks? Many teenagers drink soft drinks and buy them at school, and why shouldn't they? In my opinion, German schools should be allowed to offer soft drinks; let me explain why. Firstly, the fact is that if students want sodas [NB - "soda" is an Americanism in this context] and cannot buy them at school, they will bring soft drinks from home. Secondly, it cannot be denied that soft drinks are unhealthy and do not quench your thirst. [Although this doesn't look like a supporting argument to your thesis? Maybe use "On the one hand ... on the other ..."] In the end, everyone should decide for themself [NB this usage of "singular they" is not popular with some people, who might prefer the rather gender-loaded "himself", although I find the word useful and established] whether to buy sodas or not.
