Concluding Sentence

Is a concluding sentence necessary for this paragraph?

Slavery is forced labour. It is contingent upon at least, and typically, two classes; the victim, and the master who forces the labour. This labour can be as simple as washing clothes, yet is usually more strenuous than not as the definition suggests. In a slanderous manner the victim could be your washing machine, however the more literal manner is anything living and breathing.

I am writing a paper about slavery and would greatly appreciate any help! I would like to thank whomever takes their time to lend a helping hand!

Thanks!!
