Kinda got up to speed, but may have really missed some points
Forgive any incorrections/already addressed areas
Sure - most people will save a baby from a fire, try and protect the weak and innocent - but that could simply be down to instincts 'built' into our brains. Its not our thought actions, its a
reflex action, no real thought process involved.
Why do we scream or cry if not to attract attention and help? What would be the point in tears if not to alert others to our distress. These basic signs are inbuilt - and they have some basic reactions in all of us - only those with the pyschotic mind will ignore them! So when faced with extremes to others of our own, we will respond to aid in any way possible.We even respond to other animals distress cries, and try to aid those as well. Its a natural compassion for other living beings when they are in states of great distress or pain.
However, homeless people often do not have the screams and agony shouts of imminent life threatening situations going on, but if they do - they would certainly generate the same response to anyone else - because they are human. When it comes to a compassion of a different time, the trouble isn't imminent danger - its a long way off. If you knew a homeless person who you were walking past would die if they didn't get food - nearly every single person would help them out. However, they are not necessairly dying with an imminent threat to their lives (well, not the homeless round here in Leeds anyway, they are all beggars - and earn up to £150 a day begging on the streets - and it all feeds their drug addictions. There are charities, and services that help them out - but they tend to shun it instead....so some do chose to stay this way, because its what they want).
The reason why some don't give money - simply because we either do not believe their plight (as in Leeds!), or alternatively, its probabily more along the lines of 'someone else will sort it' - which unfortunately is a human trait worldwide.
The homeless will receive the short term help when in extreme danger - same as everyone else - its the longer term charitability that is needed which they probabily won't get. It also requires a long term commitment to help themselves as well, which many do not seem to do!
