While conducting an interview if a candidate speaks about his/her disturbing past, will you be affected and get carried with emotions?

May affect the nomination, but must focus on the interview itself and the real purpose for which they come

no, just focus to why you are there as interviewer, to know the qualifications and the competence.
in other way it affects maybe your decision because the candidate maybe still can't move on from his/her disturbing past that may have affect to his/her performance in future.
Just show to the candidate your understanding so that he/she will not felt ignored.

Personally we can but not in proffiessional, who is the best deserves the rights 

If HR team feels that past will not interfer with any future obligation towards the role for which the person is being hired than you should not be, In case it will you know what to do.

In an interview, candidates should be assessed in a fair, impartial and objective manner.
Emotions and feelings are personal and prejudiced and these can cloud what should essentially be a business decision.
Having said that, there is such as thing as a hunch honed from years of people management. 
And sometimes a "trained" hunch can really save a company from a bad hire.

Looking kingly into situation like this the interviewing of five or ten students an never be the same due to the the different ways they do interact to them at the time of the interview and ideas raised up by the students.I think emotions comes in depending the type of questions being posted to the candidate ( about the his/her life style or background ) by so doing the candidates is force to tell all his/her worries in life then you now begin to fell and have sympathy for that forgetting to kn ow the main reason and why he.she is insde there for. So interview should only base on the main things concern at the moment in order to avoid emotions and forcefuuly change of mines to the wrong side
