The mindset of most people or Countries who withdrew their aids from people or Countries they should have help is because they didn't see the possibility of profiting from the situation,
For instance , Politicians tends to help the masses during election season just to gain the sympathy of the public so during election proper the electorate will consider voting them
Most celebrities and wealthy individuals help the poor because it will make them more popular by putting them in the limelight for the right reasons and gaining more relevance in the society
Some rich countries help poorer countries because of what they stand to gain especially when the poor country is endowed with natural resources,
The Rwanda genocide would have been prevented if Rwanda had natural resources then, the West refused to step in because there was nothing to gain from the massacre.
The bottom line remains that most people give help because of what they stand to gain whether you're succeeding in life or not, nobody likes investing in an unprofitable venture
such habits listed above should be discouraged in our society. You need not to benefit from your good deeds and helping hands. Some good deeds are for the sake of the society. Everything must not be for selfish interest. I understand we're leaving in an evil world. But we the good ones must show commitment that we can make a change. For others to emulate.
Helping people in need or crisis should be our habits, though, we don't pray for crisis. We Pray for peaceful co-existence. But crisis is inevitable.so we have to help those that are in crises within our reach
