Where is the Place of 'Nature' and 'Nurture' in a Child's Development?

The above question goes to every parent, teacher, mentor and anyone that could influence the growing child; where is the place of nature and nurture in the child's development?

Which is likely to have a stronger hold on the grown man/woman?

How do we (parents, teachers.....) fail to notice the inhumanness at the early age? I believe if it is noticed early enough, the child character could be remodelled with corrective measures and show of care.

Hopefully, a look at this photo will make you wonder at the LIFE EXPERIENCES/ISSUES people have to face and give a thought to the questions above.... Honestly, the individual with a brutal personality  today was probably once a child with calm disposition.

Look forward to reading your views...... Cheers!
