Whatever I understood after going through various explanations provided in bits and pieces, here I summarised them as below :
.
"
Responsible for" is an ownership position. You own that task that you are responsible for.
To be responsible for someone/something is describing your responsibility. Like being responsible for somebody's welfare, or being responsible for taking out the rubbish.
.
"
Responsible to" is a submissive position. The direct object (that you are responsible to) holds you accountable for your task.
To be responsible to someone/something is describing who or what you answer to or have an obligation to. Like a politician is responsible to the people who elected him/her.
.
The differences lies in the interpretation of the meaning. Hope that helps.
