It is really good to stretch forth a helping hand to those in Needs, even the Bible stresses it, " the hand of the giver will never diminish as he or she will flourish in his way and his heavenly father will shower more affection toward him.
The truth is everybody in this world gives, it is just that how, why, when and what constitute our giving habit is quite different from one others base on our discerning sanity Or rather our experience through life. Someone that refused often won't find it difficult to give while the other that never or hardly received might decide not to give because our experience often shaped us how we act and believe in our day to day activities. We often categories some people as stingy because we believe they hold unto things more than expecting or never willing to give.
Stinginess could also be mistaken for being frugal or prudent. Many of us if not all give for the purpose and mind of receiving from the person whom we give which is why we often tend to entrust our money or resources with someone that have enough with the hope of getting returns even if something went wrong. But the truth of the matter is, That is not really helpful because you expecting something in return for your kind act. Although, a situation will come where the person you helped will deem it fit to appreciate you for what you have done. So, we really need to learn giving without the aims of receiving back from the person we claimed, have helped. If you give someone for the fact that the person has assisted you that is not helping, it is simply a compensation.
I know, we all have different opinions as far as this topic is concerned. I will like to stress my point using a story of a friend of mine who was privileged to work in a hospital as a cleaner after his mother died which left him all alone by himself with others siblings his mother left behind. Before then his father had died in fatal accident that claimed many lives. He had to struggle for himself and still need to fend for the junior ones. After working in the hospital for two years, there a female doctor met with him knewing he was so young(14) then, how could you work here in this your age, said the doctor. He narrated what had happened to him in details.
The doctor took pity on the boy And asked if he was living alone which the boy responded no, I was staying living with a family that helped me to get this job,' he had said softly. Before that time she met my friend she had had issues with her house maid.
After some weeks my friend decided to pack in the woman house. Though the woman was happily married but she wasn't living with her husband who lived in another state. The woman only got to see her husband at weekend after the week work. 
Without prolonging the story, she agreed to assist my friend with half of his school since he was still working in the hospital at the time my friend was with her. After a year the woman retired and left to meet her husband while my friend was still in school though the woman never stopped assisting my friend with stipend but many a time the woman will call my friend to come down their to work ( to keep the house clean amongst others.
My friend managed to graduate and even before he had been sending money to the woman just to appreciate what she had done in his life because without her he might not have achieved what he really had achieved. But the trouble is too much had the woman would want my friend to always come and watch clothe and do some other housechores even when she knew he had a lot now as he had grown up now, he still needed to cater for the youngers ones.
Besides the woman, there had been others who had helped my friend back in the school who never asked nor trouble him like the woman used to do.
If you are strict or being discipline is quite different from being wicked.
