General Paper

can someone help me in constructing introduction for the following topics,

1. 'The society is solely to be blamed for the corruption of its youth.' Is this true?
2. 'Violence is never justifiable'. What is your view?
3. 'Is a longer life expectancy always desirable?

i need a paragraph of introduction

i wrote one but badly written,

1. Corruption have been rising especially by the youth and society is often blamed for. It is true that the society is at fault for the corruption of its youth, but to say so, is to ignore the fact that other factors such as greed and poverty can cause corruption.

thanks
