Three necessary evils that can ruin a man

Money is not an evil because we need money for our existence but like you said one should have some ethics while making money .. Hunger for power is evil and can ruin a person because with it come other qualities like violence,arrogance and so on..

Money is definitely necessary for living as long as Money earning remains well within limits. You are right Greed makes a man an animal. The other evils that a man or women are Arrogance, Ignorance and harshness.

Power and possesiveness can be another two evils.

Power to do certain thing is good but it can be used for wrong purpose as well , where it becomes evil

similarly possesiveness is good as it helps you to achieve goal in life, however certain things are not achievable by possesiveness and it become evil when a person gets too much obssesive.

I would say limited amt of everything is necessary..be it love passion attitud angerr etc... it's when you cross the limit that it becomes an evil.

As poet kabir das had said "ati ka bhala na barsna, ati ki bhali na dhoop...."

I would say money, power and position are all good when used in right direction for the betterment of their own standard as well as for others progress. These three will eventually turn into evil when acquired unfairly and controlled dictatorially. There is basically a thin line between these to be good or evil. It all depends upon the basic mindset of the person how to be within a limit with all the three in their favour.

For me the three evils that ruin a man are - 1. Misuse of his power and money

2.  compromising with his inner voice/ethics for materialistic gains.

3 Ceasing to learn and adapt.

1) Power being misused.

2) Laziness.

3) Excessive money which may lead to laziness and negative thoughts.

Necessary three evils are

1. Money in excess leads to greed
2. Power excess makes man an animal
3. Last but not least marriage because no person says he wants to marry or he is 100%happy in his marriage but he should marry for the beautiful gift ,their children.
