Hello,
As you said you are more interested in Ethical hacking and want to make this your future. But To become a good Ethical Hacker you need to have strong catch on the following languages:
C
C+
PYTHON
RUBY
.NET
PHP
ASSEMBLY LANGUAGES
TCP/IP PROTOCOLS LIKE SMTP, ICMP and HTTP and Many more.
You should have knowledge of linux.
You will work in certain company that will hire you but they want a bachelor degree with above knowledge and good soft skills.
My suggestion is Do Enginerring in IT/CS that will enable you to get to know about the programming languages. Mean while during your Engineering you can join various courses for Ethical Hacking. Without Knowing Programming you can not get into Ethical Hacking.
Good luck.
