Fraternities are an awesome way to meet people and have a great time in college. What frat are your pledging?
As to the hazing... I'm in a fraternity that hazes hard. From an outsiders perspective, it looks like sadistic abuse without a purpose.
After going through it myself, I can tell you that it has had a very positive impact on my life. It strips away the innocence of the world and truly makes you appreciate many things you previously took for granted. It's a very humbling experience and after going through it, any task/problem is an easy issue to tackle in comparison.
And it keeps pussies out of your frat.
